Eternal War

Valkyr Warcry Augment that extends the active ability’s duration when Valkyr gets melee kills.

Released Apr 1, 2015

Eternal War adds time to Warcry for each melee kill while Warcry is active. Consider it for a Valkyr setup that can keep securing melee kills during Warcry and benefits from extending the ability without relying only on its initial duration.

Understand Eternal War

Useful when…

  • Use it when melee kills during Warcry are a regular part of your combat pattern and maintaining the ability longer is useful.
  • Consider its rank investment if you want more duration added per qualifying melee kill.

Effect and condition

While Warcry is active, each Melee Kill increases its duration. The bonus is 1.25 seconds per kill at rank 0, 1.75 seconds at rank 2, and 2 seconds at rank 3. The kill must occur while Warcry is active; the listed effect does not describe duration gains from kills outside that window.

Fit and installation

This is a Valkyr Mod augmenting Warcry. It occupies a standard slot, has Zenurik polarity, and has a base drain of 6. Its benefit is tied to melee kills, so it fits a setup that can continue landing those kills during Warcry. The supplied properties list no incompatible names.

Rank investment

The effect rises from 1.25 to 2 seconds added per qualifying kill across ranks 0 to 3. Example fusion costs are 30 Endo and 1,449 Credits from rank 0 to 1, then 120 Endo and 5,796 Credits from rank 2 to 3. If your melee kills are frequent enough for the extra time to matter, higher ranks improve each extension; if kills are infrequent during Warcry, the augment’s central condition is less often met.

Other Valkyr augment effects

The listed alternatives affect different abilities: Prolonged Paralysis changes Paralysis by pulling affected enemies toward Valkyr and increasing stun duration; Enraged changes Hysteria damage and critical chance while imposing a duration and matching cooldown; Swing Line changes Rip Line’s airborne Energy cost and adds Parkour Velocity. They do not provide Eternal War’s Warcry duration extension.

Limitations and tradeoffs

  • The extension requires melee kills while Warcry is active.
  • Higher ranks increase the time gained per qualifying kill, with additional fusion costs.

Common mistakes to avoid

  • Expecting kills before Warcry is active to extend it.
  • Treating the listed 2-second extension as the rank 0 effect; rank 0 grants 1.25 seconds per kill.
