Endless Lullaby

Baruuk Lull duration and recast augment

Released Feb 4, 2020

Endless Lullaby extends Lull's duration and lets a finisher or kill on a sleeping enemy retrigger Lull for a portion of its remaining duration. Consider it when you can reliably act on sleeping enemies to sustain the ability.

Endless Lullaby GUIDE

Understand Endless Lullaby

Useful when…

  • Extending Lull through finishers or kills on sleeping enemies.
  • Increasing Lull duration without relying on the retrigger condition.

Effect and trigger

The mod grants +50% Lull Duration. When Baruuk performs a finisher on or kills a sleeping enemy, it retriggers Lull for a portion of the remaining duration. That portion scales from 25% at rank 0 to 100% at rank 3. The retrigger depends on acting on an enemy while it is asleep; the passive duration bonus does not state that condition.

Compatibility and investment

Endless Lullaby is a Zenurik-polarity standard mod for Baruuk, with base drain 6 and maximum rank 3. The passive +50% duration is listed at every rank, while ranking improves the retrigger percentage. The example rank 2-to-3 fusion costs 120 Endo and 5,796 Credits; the final rank is most relevant if you value retriggering the full remaining duration.

Other Baruuk augments

Reactive Storm modifies Desert Wind with +250% Status Chance and damage that changes to match enemy weaknesses. Elusive Retribution instead builds Melee Attack Speed and Melee Critical Damage when Baruuk eludes attacks, up to six stacks lasting 6 seconds. Both serve different ability or combat patterns; neither adds Lull's duration or sleeping-enemy retrigger.

Limitations and tradeoffs

  • The retrigger requires a finisher or kill on a sleeping enemy.
  • The passive duration bonus is fixed across ranks; rank investment chiefly improves the retrigger fraction.

Common mistakes to avoid

  • Expecting Lull to retrigger without a finisher or kill on a sleeping enemy.
  • Assuming ranking up increases the listed +50% Lull Duration passive.
