Abilities 6 of Astral: Ancestor Eater

Unarmed

You trigger an Unarmed ability by attacking the intended target with an Unarmed Attack. If you do not have the Proficiency to use Unarmed Attacks, or that arm is Maimed, you cannot use the ability.

Decay

You cannot benefit from Preserve or Recover. Effects that restore Hits (e.g., Drain Damage, Heal, Share) cannot increase your Hits beyond one.

A Twin ability includes the "Twin" prefix as part of the tagline and is delivered by attacking two separate characters with separate weapons in either hand. Both characters hit are affected. If the same character is hit by both attacks, that character is only affected once. If this makes the target ambiguous (e.g., Twin Disarm on two different weapons or Twin Maim on two limbs), the affected character chooses which target is affected.
