Behaviour and interactions

Surviving damage crossing below 25% maximum HP grants 30 × log2(1 + rank) shield for 4 seconds, with a 30-second interval. Lethal damage remains lethal; this is not a cheat-death effect.

Tier: Legendary · Categories: Survival, Utility

Restriction: Surviving damage crossing below 25% HP; once per 30 s.

Rank scaling from source

n = rank, q = rank − 1, l = log2(1 + rank), h = log2(rank), for rank ≥ 1. The excerpt below is copied as text, not executed. Primary/secondary meaning is defined in the resolver description and behaviour notes.

v.Primary=30*l;v.Secondary=.25;v.Duration=4;v.TriggerInterval=30;break;

Acquisition ranks have no authored balance cap; integer/float representation and bounded runtime effect rules still apply. Spare Charge is ranked per selected normal active. Run upgrades survive stage travel and downing, and clear at final run end.
