Otherworld Legends: How to Trigger Uliana Endothermic Rupture

To trigger Uliana's Endothermic Rupture passive in Otherworld Legends, you must build up frost on an enemy with cold attacks until they reach their chill threshold, then strike them with a heavy finisher. The passive detonates the stored cold energy into an area-of-effect ice burst, dealing heavy burst damage to the primary target and splashing residual damage across nearby enemies.

Trigger Requirements and Detonation Mechanics

Endothermic Rupture requires a two-step sequence: priming the target and detonating the mark.

Frost Priming: Land consecutive normal attacks or active ice skills. Visible frost markers accumulate on the enemy as they take cold damage. A single stray hit does not trigger the burst; the target must reach the required cold threshold first.
Finisher Impact: Once the mark is primed, strike the enemy with a qualifying heavy attack. This can be the final blow of Uliana's standard basic attack combo or a direct hit from an equipped secondary skill.

When the heavy hit lands on a primed enemy, the frost collapses inward and ruptures. In clustered packs, adjacent primed enemies caught in the blast radius will also shatter, creating overlapping bursts.

Combat Sequence to Guarantee Triggers

The most common failure point is dodging or canceling your attack animation too early. If you break the basic combo chain before the final swing connects, the rupture check fails to resolve.

Execute this sequence to land the detonation reliably:

Open with a Dash Attack: Slide into the target group to apply the initial frost charge and stagger the frontline.
Deliver Light Attacks: Perform two to three light strikes to build the enemy's frost gauge up to the rupture threshold.
Commit to the Finisher: Let the animation complete on the final basic attack input without dodging. Watch for the visual ice flare on Uliana's weapon to confirm the heavy swing connects.
Chain a Secondary Skill: If an elite enemy survives the initial burst, immediately cancel the recovery animation into your secondary skill to strike with an instant follow-up detonation.

Synergies and Item Priorities

To trigger Endothermic Rupture more frequently, prioritize build elements that accelerate your combo cycle and status application:

Stat / Item Focus	Combat Function	Rupture Benefit
Attack Speed	Increases swing cadence	Reaches the final combo finisher faster, reducing vulnerable recovery frames.
Status / Chill Boosters	Increases frost application	Lowers the number of preliminary light hits required to prime the target.
Critical Strike Items	Enhances burst multipliers	Scales both the qualifying heavy finisher and the resulting passive detonation.

Position Uliana toward the most durable enemy in a room, such as an armored elite. Herding smaller mobs around that target ensures that your combo finisher primes and detonates multiple rupture bursts simultaneously across the entire pack.
