How to Spawn Ultimatum Boss? Ultimatum League

Location: Level 78+ in endgame maps, wave 10
the Trialmaster spawns 1 time in 50 maps

It's worth noting that The Trialmaster (wave 10) can only start showing up at area levels 78 and above.

The completion rate of the Trialmaster encounter is only 60%! Part of this could be attributed to the fact that players may have only fought him a few times and are still learning the encounter as they go, though the Trialmaster is a fairly difficult encounter for most, as many of his abilities can be extremely dangerous, particularly when you factor in map modifiers and Ultimatum modifiers.

64.39% of all generated Trialmaster encounters were never even started. What this means is that players either failed an encounter prior to wave 10, took their rewards prior to wave 10 or didn't start the Ultimatum encounter altogether. When we look at the best case scenario where the Trialmaster spawns 1 time in 50 maps and then factor in the realised encounter rate (35.61%), we see that the average player in level 78 or higher maps is actually fighting the Trialmaster 1 time in 140 maps. Some players have said that they feel the Trialmaster is too rare. Our investigation while generating these stats showed that those players are often not playing through to wave 10, failing encounters, or not even starting the encounter to begin with.

Defeat Ultimatum Boss - Trialmaster’s Domain: Double or Nothing

In the endgame, Inscribed Ultimatums indicate an offering you must bring to the Trialmaster’s Domain. If you’re able to succeed at the inscribed challenge, the Trialmaster will reward you with an item of roughly double value. But if you fail, you forfeit the offering that you put on the line. Inscribed Ultimatums come with a challenging assortment of Ultimatum difficulty modifiers and can be traded to other players.

Sacrifice your offering

Trialmaster's Drops

Yaomac's Accord Vaal Sceptre

As the difficulty of the Trialmaster’s encounters escalates, so too do the rewards. In addition to some of Path of Exile’s most valuable items, you might be offered new Ultimatum-exclusive Unique items.

PoE has designed Ultimatum league to be very compatible with party play – each player gets their own rewards, can vote on difficulty modifiers and can choose whether they want to risk the next round or not.

The Trialmaster

In the Ultimatum Challenge League, you'll test your skills in the trials of Chaos. In every area, you'll encounter The Trialmaster who will present you with a reward, objective and choice of three modifiers that add extra challenge to the encounter.

Trialmaster PoE

If you're successful, you must then choose between accepting the reward you've earned or attempting additional trials with increased difficulty in the hopes of earning additional rewards. Choose wisely, because if you fail, you'll lose all the rewards you've earned so far. Each encounter with the Trialmaster provides a series of trials with increasing difficulty.

In maps, you'll occasionally find Inscribed Ultimatums which can be placed in the map device to transport you to the Trialmaster's domain. Each Inscribed Ultimatum specifies an offering that you must bring with you, a reward you can earn and an assortment of Ultimatum difficulty modifiers. If you're able to complete the Trial, you'll earn the specified reward. However, if you fail, you'll forfeit the offering you brought with you.

Trialmaster’s Trial: Risk it All

The Trialmaster offers you a reward and a challenge with three difficulty modifiers to choose from. There are four possible objectives:

Defeat waves of enemies: You need to kill a certain number of enemies to get success.
Survive: Don't die until the timer runs out.
Stand in Stone Circles: You must stand in each stone circle for a certain period of time.
Protect the Altar: Kill enough enemies without letting the altar be destroyed.

Select Ultimatum Mods

If you succeed in his trial, you may claim your reward. However, you’ll be presented with an Ultimatum: leave with your spoils, or attempt more challenging encounters for more valuable rewards.

PoE Ultimatum Guide

But be careful how many trials you undertake – if you fail, you’ll lose everything you’ve earned so far.

Ultimatum Trials of Chaos Modifiers

Player need to select a mod to increase the difficulty of the trial, and then perform various Challenge Types. After finish a wave successfully, player can choose to leave the trial with the loot, or enter the next wave. But be careful how many trials you undertake - if you fail, you'll lose everything you've earned so far.
