Changes how Fire Walker plays: Fire Walker Augment: Accumulate 250% of the damage Fire Walker deals, unleashing it in a trail of fire that lasts 10s.
Higher ranks usually improve the key magnitude or duration of the augment.

Equip Pyroclastic Flow when that change is part of your standard Nezha 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 Nezha 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 — Pyroclastic Flow often only feels complete at rank 3.
Try one mission with and without it on Nezha before locking the slot.
If you Helminth over Fire Walker, this augment usually becomes irrelevant on that loadout.
