Impervious FAQ

What does the Aquaconda fix tell me about poison?

Read the named attack and enemy forms together: the 1.1 correction covers Poison Spit from Aquaconda+ and Aquaconda++. It establishes that those attacks should no longer bypass Damage Resistance or Impervious, not that every poison source is harmless or that all Aquaconda attacks share one damage rule. Official 1.1 notes

How should I use the time before delayed damage arrives?

Plan an exit from the hazard before the next hit. The delay is useful only if your next action improves the situation; remaining in the same attack can keep adding danger while the health display is catching up. Pair the defensive choice with a reachable escape or recovery opportunity, and judge no-damage goals by their own conditions.

Avoid a circular Self Predator plan

In a May Self Predator discussion, players first suggested Impervious for self-damage, then corrected the advice because the achievement was itself needed to unlock Impervious. Arc reported earning the achievement with Antlers instead. This is a historical player-reported unlock relationship, not an independently verified current unlock condition; inspect the locked card before building a route that depends on already owning its reward.

Does that report establish a Common-only Antlers requirement?

The same thread contains conflicting advice about keeping Antlers at Common rarity: CecilHorns proposed it, while KingOfCharge said it was unnecessary. That disagreement does not justify a mandatory Common-only rule. It also gives no complete formula for how Impervious’s delayed damage interacts with every self-damage trigger.
