PoE Monster Mods and Archnemesis Mods 3.20

Say Goodbye to Archnemesis

The Archnemesis monster mod system has been replaced with a system that more closely resembles Path of Exile's initial monster mods, but with modernised balance and effects. This system has been streamlined so that each modifier only does one specific thing and describes exactly what it does. While you'll still encounter modifier combinations that get your heart racing, these will be rarer than before and easier to understand in the heat of combat. Changes to rare monster rewards mean that you don't need to summon a magic find culling character to help you with specific monster mods anymore.

The original motivation for developing Archnemesis was that the previous monster mod system was very out of date. Many of the mods didn't have any appreciable effect under modern balance and there wasn't a lot of interesting gameplay possible. In our opinion, Archnemesis did succeed at adding a lot of interesting new mechanics to rares, but introduced the problems described above. While creating the new monster mods described, we were careful to retain most of the interesting mechanics that Archnemesis introduced, but in a way that doesn't include a grab-bag of other effects and is diluted by many other simpler mods.
The result is a system that is very similar to what monster mods used to be like, but with much more up-to-date content and balance. Mods are simpler and say exactly what they do. While you can certainly still rarely encounter scary combinations of mods that really wake you up, it's a lot rarer than it was under the Archnemesis system. We feel that the new system is more modern and interesting than the old monster mod/nemesis system and is clearer and easier to understand in the heat of combat than Archnemesis was.

Monster Mods and Archnemesis

Problem:
Archnemesis monster mods each added a number of stats and buffs to monsters, causing them to feel overwhelming and confusing (especially when multiple mods were present on the same monster).

Solution:

Monster mods now only do one specific thing.
Here's an example: The Magma Barrier Archnemesis mod did a whole lot of stuff. It started by putting a magma barrier around the monster, but it didn't stop there. It converted some of the monster's physical damage to fire damage, it added some extra fire damage on top, it granted fire resistance to the monster and it gave some physical damage reduction for good measure. It also spawned volatile flamebloods to follow you. The new equivalent modifier just puts a magma barrier around the monster and does nothing else.

Problem:
Keyworded, thematic monster mod names gave an impression of the overall effect of the mod on the monster but did not explain exactly what they granted, requiring players to memorise them.

Solution:

Monster mods now say exactly what they do.
For example, rather than "Incendiary", which broke down into six properties, you'd now see monsters with either "Ignites" or "Fire and Ignite Resistant". Instead of "Deadeye", which did five separate things, you'd now see "Applies Random Mark", "Extra Crits" or "Accurate" as separate unrelated mods.

Problem:
The percentage of Archnemesis mods that significantly changed gameplay was high, and combinations of modifiers that required careful play arose too frequently, making content too complex.

Solution:
Since each mod now only does a single thing but monsters don't have more mods than they used to, the percentage of monsters with gameplay-altering effects is now much lower. Interesting and challenging emergent behaviour from overlapping mods can still happen, just less often.

Problem:
The way Archnemesis rewards were set up meant that many players felt like they couldn't just kill a monster, they had to consider if they wanted to bring a magic find character in to maximise rewards

Solution:

Players are no longer required to do annoying actions to maximise rewards
In Archnemesis, rewards were associated with individual mods. This meant that you could tell what kind of rewards you would get in advance. In some cases, you were then effectively required to fetch a magic-find culling character to make sure that you maximised the value of the monster mod that you had found. In other cases, you would ignore a monster completely if you knew that it would only drop rewards that were of no value to you. In the new system, we have added a significant pool of new rewards to rares, but the reward that is on the monster is hidden (and not associated with a specific mod), so you don't know what kind of rewards you will get until you kill the monster. Rare monsters with more mods are more likely to have these special hidden reward mods. This new reward system smooths out the spikiness that the Archnemesis reward system had.

In our 3.20 expansion, Archnemesis will be replaced with a system that is more similar to the way monster mods worked in the past.

The issues that players often had with Archnemesis were:

The keyworded mod names were not fully descriptive of what they did
The mods often had multiple effects bundled which made them harder to understand
Due to how many effects were included in a single mod, it made too many encounters too complex
The way Archnemesis rewards were set up meant that many players felt like they couldn't just kill a monster, they had to consider if they wanted to bring a magic find character in to maximise rewards

The goals of the new system are:

Mods do one specific thing
Mods say what they do rather than having a thematic name you must learn and remember
Encounters are simplified on average while retaining interesting fights
Players are no longer required to do annoying actions to maximise rewards

Let's examine those goals individually:

Mods do one specific thing

Instead of "Deadeye", which did five separate things, you'd now see "Applies Random Mark", "Extra Crits" or "Accurate" as separate unrelated mods.

Encounters are simplified on average while retaining interesting fights

The pool of mods that involve complex interaction (like spawning volatiles or ground effects on death) have been heavily diluted by the presence of the simpler mods. This means that you encounter more complex fights less frequently. But interesting and challenging emergent behaviour from overlapping mods can still happen, just less often.

Players are no longer required to do annoying actions to maximise rewards

In Archnemesis, rewards were associated with individual mods. This meant that you could tell what kind of rewards you would get in advance.

Monster Mods FAQs

Since the mods are simplified and separated, does that mean rare monsters will now have more mods on average to compensate? How many mods can a rare monster have now?

We're currently playtesting the new monster mod system to determine this. At the moment it's 2-4, but this may change as we continue to iterate.

Will the modifiers' effects be made more intense to compensate for their simplification?

These are new mods that have similar themes to old ones, but have new balance values. In many cases these are the same as before, but we're evaluating on a case by case basis. It's mostly the weaker secondary mods that need to be juiced up so that they make sense as a standalone mod.

Are rare monsters still getting increased damage/hp/defenses per mod or only whatever the individual mods on the rare roll?

Rare monsters never received additional damage per incremental mod, and the only defenses they received was a life bonus (on top of whatever the mod actually did of course). Under the new system, they will get life, experience, item rarity and quantity bonuses per additional mod.

Will the changes made to reduce the number of rare monsters spawned in various mechanics be undone now that each individual rare encounter is less likely to be a major burden to the player?

No.

Will Pantheon mods still exist with simplified lines such as ''Uses Kitava's Skills'' or something like that?

Pantheon mods still exist but are very rare.

Will stealing ''Ignites'' make all our hits ignite?

This makes all monster fire damage ignite, so it makes all your fire damage ignite if you steal it.

Is this a nerf to Headhunter? Will mods be able to stack like they could before Archnemesis?

Mods will not be able to stack (as many can't function when stacked). There are more mods to steal, which is a buff to the upper end of Headhunter gameplay.

Can we have examples of some of the new reward types being introduced?

Not yet.

Does this mean I'm forced to play Magic Find all the time now?

If you're able to sacrifice character power for magic find then, you'll find more and better items. That was true before 3.19 and is the nature of magic find in Action RPGs. Note that magic find has diminishing returns, so a small investment can go a long way.

How have reward conversions changed?

We're still working on this, but we can confirm:

Only some of the new rewards are conversion ones
We are removing the undesirable ones like conversion to flasks
We are trying to make the rewards from rare monsters not so all-or-nothing

Does Magic Find still massively affect the reward conversions?

We are still iterating on these systems and don't want to set expectations around this in either direction just yet.

Archnemesis Changes 3.19.0d Patch Notes

Increased the item rarity for monsters with two Archnemesis modifiers, and substantially increased the item rarity for monsters with three and four Archnemesis modifiers. With the item drop conversion system, this results in a lot more powerful drops when hitting certain combinations of modifiers. This also results in a lot more Unique items from monsters with three or four modifiers.

Archnemesis and Rare Monster Changes 3.19.0c Patch Notes

Lowered the incremental life bonus that Rare and Magic monsters receive from having additional Archnemesis modifiers, and increased the base life bonus that Rare and Magic monsters receive.
The overall result of this change is that rare and magic monsters with one Archnemesis modifier have unchanged life on average. Rare monsters with two or three modifiers have 15% less life on average, and Rare monsters with four modifiers have unchanged life on average.
Monsters can no longer be found with three Archnemesis modifiers during the campaign, and the likelihood of encountering a monster with two modifiers during the campaign has been reduced.

Archnemesis Changes 3.19

We have been re-examining what role rare and magic monsters have in Path of Exile, regarding how often you should encounter rare and magic monsters, how difficult they should be to kill and how rewarding their deaths should be.

Previously, league content made fights hard by spawning a lot of rare monsters. In some cases, six to eight times the normal rate of rare monsters. Now that we have better mods available to make fights against rare monsters individually challenging, we have gone through the whole game and normalised the rate that rare monsters are spawned. Some leagues had quite large reductions in spawn rate. You won't encounter situations with dozens of rare monsters on screen at once anymore. Where necessary, we have rebalanced rewards to compensate.

In addition, Archnemesis modifiers have had their rewards reviewed. The number of mods directly correlates to increased item drop bonuses, and powerful modifiers that show up in the third and fourth mod slot use a new reward conversion system that stacks with the other drop bonuses and with player item rarity and quantity.

Lowered the number of Rare and Magic Monsters encountered through various League encounters.
Lowered the number of Rare Monsters spawned in the Summit, Gardens and Basilica Map Boss encounters.
Lowered the number of Rare Monsters spawned in Doryani's Machinarium, and the number of Rare and Magic Monsters spawned in The Coward's Trial.
Assembled Metamorphs no longer summon minions at various life thresholds.
The Ritual Tribute from sacrificing Rare Monsters has been increased, to compensate for the reduced number of Rare Monsters now spawned.
The Immune Response Atlas Notable Passive Skill now causes Blight Encounters in your Maps to spawn 50% more Non-Unique Monsters (previously 100%), and causes Blight Monsters in your Maps to spawn 100% faster (previously 150%).
The Abyssal Army Atlas Notable Passive Skill now causes Abysses in your Maps to spawn 50% increased monsters (previously 100%).
The Unspeakable Offensive Atlas Notable Passive Skill no longer causes Harbingers in your Maps to summon 60% more Minions.
The Flash Breach Atlas Notable Passive Skill now causes Breaches in your Maps to have 20% increased Area of Effect (previously 30%), and 20% increased Monster density (previously 30%).
During the campaign, Rare Monsters you encounter will only have one or two modifiers.
In Maps, you'll stop encountering Rare Monsters with one modifier, and will mostly encounter Rare Monsters with two or three modifiers. It is also possible to encounter Rare Monsters with four modifiers again.
Some of the more powerful Monster modifiers now use a special reward conversion system. For example, if you defeat a monster with the Corrupter mod, all of its drops become corrupted. The Solaris-touched mod converts all of its item drops to maps. The Kitava-touched mod will cause the rarity of its drops to be upgraded by one tier, so magic becomes rare, rare becomes unique, etc). If you're lucky, you can find these conversion modifiers on both the third and fourth mod of a rare monster. This causes them to stack together. So if you kill a four-mod rare monster with both the Entangler and Kitava-touched mods on it, its heavily juiced drops will also be converted to jewels with their rarity upgraded by a tier. Due to the high amount of inherent item rarity that four-mod monsters have, this may result in several unique jewels. This conversion system is fully compatible with your item rarity and quantity bonuses, as well as the drop bonuses from all other archnemesis mods.

The Valley of Darkness Atlas Keystone Passive Skill has been removed as a result of these changes to Rare Monster modifiers. The Stream of Consciousness Keystone has taken up Valley Of Darkness's position on the Atlas Tree.

Magic monsters have a restricted list of archnemesis modifiers compared to rare monsters, but this list still includes many modifiers which can spawn threats external to the monsters themselves, such as ground effects or volatile orbs. These external threats can feel overwhelming due to magic monsters being more numerous than rare monsters.

We have toned down the modifiers that can spawn on magic monsters so that more of them are stat-based bonuses that aren't too spammy. All monsters in an instance that are the same or very similar will have the same magic monster modifier, rather than rolling a different Archnemesis modifier for each monster.

The following Monster modifiers can no longer appear on Magic Monsters that aren't in packs: Consecrator, Flame Strider, Frost Strider, and Storm Strider.
The Corpse Detonator, Ice Prison, and Mirror Image Monster modifiers can no longer appear on Magic Monsters.
Magic Monsters with the Storm Strider modifier no longer trigger a Lightning Mirage when Hit.
Magic Monsters with the Flame Strider modifier no longer trigger an Inferno Bolt when Hit.
Magic Monsters with the Frost Strider modifier no longer trigger a Snow Bolt when Hit.
Magic Monsters with the Sentinel modifier no longer trigger a Delayed Reckoning when Hit.
Magic Monsters with the Assassin modifier no longer teleport to distant Enemies creating a Smoke Cloud.

The following Archnemesis modifiers have been renamed to make their function slightly more clear from their name:

Evocationist has been renamed to Prismatic.
Dynamo has been renamed to Electrocuting.

Problem: Monsters with block chance generally take a small percentage of incoming damage when they block rather than no damage at all, to prevent blocking feeling too punishing for players. However, Archnemesis modifiers that grant block chance prevent 100% of blocked damage.

Solution: Monsters with the Sentinel and Benevolent Guardian Archnemesis modifiers now take 20% of damage from hits they block.

There's quite a large jump in difficulty from the campaign to early maps as the number of archnemesis mods on monsters rises abruptly. This not only affects their average difficulty, but also how tanky they are. We are going to taper this up more smoothly so that it's a more gradual progression (and is unmodified in red maps). This will result in less difficulty and less life on average for rare monsters below red maps.

To prevent life values getting out of hand on special league monsters with archnemesis mods, we will also reduce the life bonus that each Essence grants a rare monster and reduce the bonus life that Red Beasts have. We will also review whether Betrayal content is spawning too many rare monsters.

Item Drops

Rare monsters are like regular monsters but with massive bonuses to item drops and item rarity. Due to the random nature of drops, it's entirely possible to get almost nothing one time, and a decent pile of rares or a unique item another time. Archnemesis mods are set up to have additional bonuses, and these scale up to be much larger for the really hard mods. The theory is that a hard fight results in more items. And it does, on average. Sometimes you get very little for killing a difficult rare monsters, and sometimes you get that unique item you've been looking for, or a shower of rare items. A fundamental part of Action RPGs is the wide variance of outcomes, rather than having deterministic results.

Archnemesis Recipe Guide

In the Archnemesis league, you'll build your own Rare boss fights by applying new monster modifiers to petrified monsters, found throughout every area. These modifiers add dangerous behaviours to their targets but also imbue them with valuable rewards. Each subsequent petrified monster you imbue within an area keeps all of the previous modifiers applied, allowing you to build some extremely difficult and rewarding encounters. There are over 60 new boss modifiers to discover, more than half of which can be created by combining other modifiers in specific recipes to unlock the most powerful and rewarding modifiers.

PoE Archnemesis Mods

Archnemesis is a challenge league that reinvigorates fights with rare monsters. It introduces around 60 new monster mods and allows you to customise your rare boss fights to control your level of risk and reward. These mods can be combined in over 35 recipes to create new, more powerful and rewarding mods. As you play through the league, you'll discover more recipes and learn how to best utilise them to get the most valuable rewards.

When you slay regular Rare and Magic monsters in the Archnemesis League, they sometimes drop an itemised version of a new Archnemesis monster modifier. You store these in a dedicated inventory panel so that they don't clutter your regular inventory.

Over the course of each area you play, you'll encounter four monsters that are frozen in place, petrified and bound to the Archnemesis statue. When you find such a monster, you can free it by empowering it with an Archnemesis mod. If you're able to successfully defeat the empowered monster, then you will receive the fixed reward that corresponds to that modifier.

The trick that makes this league awesome is the four petrified monsters per area.

The mods you apply will accumulate as you play through the area. When you empower your second monster, it also has the mod you applied to the first monster. This results in a fight that has twice as many dangerous mods, and twice as many rewards. Even though you received the reward from the first mod when you killed the first petrified monster, you receive a second reward of that type when you kill the second petrified monster. The same applies to the third and fourth fights in the area as well. By the time you defeat the fourth monster, you'll have received the first reward four times, the second reward three times, and so on.

Take care when picking what order you consume your mods so that you can maximise your rewards.

More than half of the available mods are created by combining other mods together on the same monster.

Arch Nemesis Recipes yield substantially more dangerous encounters and have more valuable rewards. Even if you're not completing a recipe with your modifiers, you can still combine them to get some ridiculous combinations of rewards. For example: Defeating an Innocence-touched enemy grants three currency rewards and converts all other rewards into currency. Defeating a Mirror Image enemy grants a divination card reward and rerolls all rewards three times, yielding the rarest result. Killing a Flame Walker enemy grants three weapon rewards. Killing a Toxic enemy drops a generic reward plus a gem reward. If you were to kill an enemy with all four modifiers, you'd get a total of 9 currency rewards, each rolled three times to drop the best result. But if you apply the mods in the order mentioned above, then as you kill each of the four monsters in the area, you'll receive the earlier rewards multiple times. The end result is the equivalent of getting 60 currency rewards and receiving the best 20 plus three regular currency rewards.

To prevent you having to backtrack, there are more than four possible locations where you may encounter petrified monsters in each area, but only the first four you encounter can be empowered and fought.

Monster Mods FAQs

Since the mods are simplified and separated, does that mean rare monsters will now have more mods on average to compensate? How many mods can a rare monster have now?

Will the modifiers' effects be made more intense to compensate for their simplification?

Are rare monsters still getting increased damage/hp/defenses per mod or only whatever the individual mods on the rare roll?

Will the changes made to reduce the number of rare monsters spawned in various mechanics be undone now that each individual rare encounter is less likely to be a major burden to the player?

Will Pantheon mods still exist with simplified lines such as ''Uses Kitava's Skills'' or something like that?

Will stealing ''Ignites'' make all our hits ignite?

Is this a nerf to Headhunter? Will mods be able to stack like they could before Archnemesis?

Can we have examples of some of the new reward types being introduced?

Does this mean I'm forced to play Magic Find all the time now?

How have reward conversions changed?

Does Magic Find still massively affect the reward conversions?
