Not sure if this is intended, but it no longer has an AP cost AND it still heals for 8HP without mentioning it on the tooltip. This means you can do silly things like walk on lava with Madora, survive with Comeback Kid, then heal up to full without using any AP. You can even send it to the next party member in the action queue to ensure everyone has full HP at the end of the turn at the cost of no AP.
