Ultimatums, also known as Trials of Chaos, is the league mechanic of Ultimatum league.
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.
Rarely, in high tier maps, the final wave may instead teleport you to a boss arena against the Trialmaster.
Inscribed Ultimatum
An Inscribed Ultimatum can be found as a random drop. 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 a zone that 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 a wave 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.
