Ultimatum

Ultimatum, also known as the Trials of Chaos, was the league mechanic of the Ultimatum leagues. After the challenge leagues ended, Ultimatum was not integrated in the core game. It was later integrated into a Unique Map, The Tower of OrdealsThe Tower of Ordeals

Mechanics

The Trialmaster and an altar spawns in zones. The altar displays a reward, the objective, and three modifiers to choose from. The player must select a mod before beginning the trial.

There are four possible objectives:

• Defeat waves of enemies
• 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.

Once you complete a wave, you will be given two choices: end the trial and receive your rewards, or start another wave by selecting a new modifier to add.

If you die, stay outside of the circle for too long, or receive 7 stacks of Ruin, the Ultimatum is failed and all rewards will be removed.

Each trial can last up to 3 to 9 waves, with more possible waves at higher zone levels.

At red tier maps (area level 78+), there is a chance to be offered a 10th wave, which teleports you to a boss arena to fight the Trialmaster. (1% chance at T11-13, 2% at T14+).

Inscribed Ultimatum

{il|Inscribed Ultimatum}} are obtained while completing Ultimatum encounters. The Inscribed Ultimatum requires the specified item to be offered and have a set of pre-selected mods. Inscribed Ultimatums can be used in a map device to open a portal to the Utzaal Arena, which only contains an altar. The required item must be placed on the altar to start the trial.

Unlike a regular Trial of Chaos, the entire arena is the trial zone (there is no out of bounds area) and there is only one wave that lasts significantly longer.

Partying

When facing a Trial of Chaos with other players, each player will be offered their own individual set of rewards. When an individual player fails the trial, they will lose their rewards but the trial will continue with the remaining players.

In between waves, the players will vote on which modifier to add to the next wave. The one with the most votes gets added. In case of ties, a mod is randomly chosen between them. Players have a limited time to vote, but the timer is paused if at least one party member is not present in the zone.

Version history

Version	Changes
3.23.0	Ultimatum has been added to the core game, replacing Metamorph. You will have approximately an 8% chance to find the Trialmaster and his Trials of Chaos in Maps. Ultimatum Encounters are now 10 rounds by default, though I sincerely hope you intend to last longer than 2 rounds. You now have a chance to be teleported to The Trialmaster's Arena for the 10th round in areas with a level of 81 or higher, rather than this being guaranteed. Ultimatum modifiers have been rebalanced, some new modifiers have been added and some previous modifiers have been removed. Ultimatum modifiers that previously had 3 tiers of difficulty, such as Stormcaller Runes, now have 4 tiers of difficulty. Monsters in Ultimatum Encounters no longer drop loot, other than The Trialmaster, though they still grant experience. Catalysts are now rewards from Ultimatum, and are affected by Map Item Quantity. Added a round count display between rounds in Ultimatum Encounters.
3.14.3c	Ultimatum did not go core and was removed from the game.
3.14.1	"Stand in the Stone Circle" Ultimatum encounters now have larger circles. Monsters in the "Stand in the Stone Circle" Ultimatum encounters have had their experience and drops improved to bring them more into line with other Ultimatum encounters. Capped the number of rare Monsters that can spawn per wave during Ultimatum encounters. Entrances to subareas (such as a Vaal Side Area) are now temporarily disabled while inside an Ultimatum encounter. Enabled the Razor Dance Ultimatum modifier. Added a short grace period when being teleported to The Trialmaster's arena. Improved various visual effects in The Trialmaster encounter. Fixed a bug where Monsters could sometimes fail to disappear after completing an Ultimatum encounter.
3.14.0	Introduced to the game.
