Similar in use to "Spirit Guard" or "Red Fury," but a offensive doll skill: Effectively give all friendly attuned pirates a duration of Rank 1, Rank 2, or Rank 3 Critical Strike (depending on doll tier). Could last 30 seconds, recharge could be 30 seconds, etc. Balancing would have to be done to prevent misuse and it possibly being OP. Match this with a small Attune Doll Boost (like the Forbidden Voodoo Doll) and another small boost and you have yourself a simple, desirable doll. Maybe for Isla Escondida?
