One of the few Condition removal effects in the game and also a full heal to boot. It might be a bit difficult to find a good target for it, but in a big Fellowship with a dedicated healing deck it can be a game-saver. The best target is probably the Imladris Caregiver which can still use its own healing in addition to the Athelas.
Attachment. Cost: 1.
Attach to a Dúnedain or Healer character.
Action: Discard Athelas and exhaust attached character to heal all damage on a character. You may discard a Condition attachment from that character.
