Helminth over Ice Wave — Avalanche Overguard + freeze/strip while a weapon buff and guns clear. Globe optional for hard defense.
Melee hits and freeze procs chill the room. Avalanche freezes and strips armor (aim ~167%+ Strength for full strip). Icy Avalanche converts hits into squad Overguard.
Strip / Overguard / buff potency; Duration for Roar uptime.
Replace Ice Wave. Roar is the gun generalist; Parasitic Armor if Overguard numbers matter more.
Icy Avalanche Overguard + Helminth gun buff — Globe optional.
Overguard on the point while guns clear.
Skip Globe babysitting — shoot under Avalanche CC.
