Card info
When you gain a Bound Ally, take the top card of the Ally deck and attach it to this card.
You gain the services of that Ally. When the Ancient One awakens, discard the Ally and put this card on the Ancient One. For each Bound Ally on the Ancient One, it takes one additional success to remove a doom token.
You may spend a Power token as either a Clue token or as $1.
