Changes how Warcry plays: Warcry Augment: While active, Warcry's duration is increased by 2s for each Melee Kill.
Higher ranks usually improve the key magnitude or duration of the augment.

Equip Eternal War when that change is part of your standard Valkyr loop.
Skip it for generalist builds if capacity is tighter on survivability or parkour mods.

Mission / Context	Rating	Why
Steel Path Survival / Defense / Disruption	Strong	Dense missions are where most Valkyr augments prove whether they belong in the build.
Mobile Defense / Excavation	Situational	Worth it if the augment helps hold or clear the objective faster.
Casual Star-Chart Farms	Situational	Often skippable when base abilities already overkill the content.

Read the max-rank text — Eternal War often only feels complete at rank 3.
Try one mission with and without it on Valkyr before locking the slot.
If you Helminth over Warcry, this augment usually becomes irrelevant on that loadout.
