As a Purgatorian, I have the following creature:
Level 27 Volatile Phoenix Fused with Pulse Bat Phoenix / Chaos Innate Trait: Buffet After your creatures are resurrected, enemies take damage equal to 50% of this creature's Speed. Fused Trait: Echolocation After an ally Attacks, this creature gains 7% Speed.
and have the Purgatorian perk “Life after Death”:
Your creatures’ traits are active even while they’re dead. This perk does not affect traits that cause creatures to intercept or take damage in place of their allies.
However, while this creature is dead, neither Buffet nor Echolocation activates when their respective triggers occur.
