  • Can be acquired by attaining the rank of Partner under The Perrin Sequence, or the rank of Flawless under New Loka, and spending ReputationLargeBlack‍25,000 to purchase.


  • Duration increase per kill is affected by Power Duration.
  • Each added instance of duration stacks, and can increase the active duration of Warcry up to its maximum duration taking into account Power Duration.
  • The duration extension works on any allies affected by Warcry. However, only melee kills made by the initial caster will extend the ability's duration.
  • The duration cannot extend over double its maximum, ex. If Warcry's duration is 32 upon activation, it will cap out at 64, getting additional kills after reaching this point will not add any extra time to the ability. The absolute maximum cap for Warcry is 42.3 seconds, which means that Eternal War can never raise its duration past 84.6 seconds.


  • One can cast Warcry on their squad at the beginning of a mission, which can then be maintained for the entire mission with Eternal War by rapidly melee-killing enemies, allowing the team to benefit from Warcry while keeping energy expenditure low. This is easiest to do in endless mode missions like Survival, Defense, and Interception. Care should be taken around Nullifier Crewmen and tilesets where one can easily fall off the map, as either will end Warcry prematurely.
