PoE 3.20 Changes

Impending Doom has also had its base damage roughly doubled to compensate for this loss. We have replaced the Doomsday keystone with a new Hex-themed keystone, and introduced the new Cursed Ground Support which was reworked from the Doomsday keystone.

Specifics:

• Doom Blast, from the Impending Doom Support, now deals 102 to 154 Chaos Damage at gem level 1 (previously 54 to 81), up to 1654 to 2481 at gem level 20 (previously 868 to 1301). Now has 370% Effectiveness of Added Damage at all gem levels (previously 200%).
• The Doomsday Keystone Passive Skill has been replaced with the new Hex Master Keystone. This Keystone provides "Your Hexes have infinite Duration" and "20% less Effect of your Curses."

Skill functions and interactions

Doom Blast is considered a spell, therefore modifiers to spell damage apply to it.

Doom Blast is triggered when a hex ends, and its damage benefits from bonuses of the ending hex. E.g. the reduced chaos resistance from Despair.

The Doom mechanic causes a self-cast Curse to increase in intensity over time until it expires. This works well in conjunction with the Impending Doom support, which causes an explosion of chaos damage when a linked curse ends. Curses have also received a new look.

Doom Mechanics

PoE 3.20: Doom has been removed.

If the Hex was self-cast, the curse will gain Doom over time. Doom increases the effectiveness of the curse (1% per Doom). Maximum Doom is capped at 30 by default. Each Hex has its own Doom counter.

Frostbite	Curse gains 10 Doom per second if you Cast this Spell yourself

The new Doom mechanic causes a self-cast Curse to increase in intensity over time until it expires. This works well in conjunction with the Impending Doom Support, which causes an explosion of chaos damage when a linked curse ends.

Doom Passive Skill

1. Doom Cast

Doom Cast is a notable passive skill that grants increased critical strike chance and additional critical strike multiplier for spells.

• 60% increased Critical Strike Chance for Spells
• +15% to Critical Strike Multiplier for Spells

2. Doomsday

Doomsday is a keystone passive skill that modifies Hex spells. When casting the Hex spell, instead of applying the curse which gains Doom over time, the spell creates a Hexed Area for 1 second. Enemies in the Hexed Area receive the curse, and after 1 second, the Hexed Area expires and applies the maximum amount of Doom to enemies standing in it.

• Your Hex Curse Spells create a Hexed Area for 1 second if you Cast them yourself
• Enemies in the Hexed Area are Hexed, and the Hex does not expire while in the Hexed Area
• Hexes applied this way do not gain Doom over time
• Hexes in the Hexed Area gain up to maximum Doom when the Hexed Area ends

3. Faster Doom Gain

Hexes Have 50% increased Doom Gain Rate

4. Skittering Runes

Skittering Runes is a notable passive skill that grants increased effect magnitude for curses.

• Hexes you inflict have +10 to maximum Doom
• 10% increased Effect of your Curses

5. Whispers of Doom

Whispers of Doom is a notable passive skill that raises the active curse limit by one.

• You can apply an additional Curse

6. Malicious Intent

• Hexes you inflict have +4 Doom
• 20% increased Damage with Hits and Ailments against Cursed Enemies

Impending Doom Support and Doom Blast

Impending Doom support gem triggers Doom Blast when the Supported Hex on an enemy expires, causing an explosion of Chaos damage based on the level of Doom that has accumulated while the Hex was active.

Impending Doom Support Build Example

Curse skills were often used via automatic triggers or application. With Path of Exile: Heist‘s rework to curses, the idea is to encourage players to self-cast them more often as they’ll grow in intensity over time after being cast. There will also be new and reworked gems that interact differently with curses.

One example is Impending Doom, a support gem that makes cursed enemies explode once the curse’s effect ends. This will only work on self-cast curses whether it’s from the end of the duration of the spell or because the player removes the curse prematurely (or applies a different curse).

Does Impending Doom work with Curses cast by Bane?

It currently doesn't but that's not 100% locked in.
