Troymk1 said: each single card of Athelas is maxed out at 5 healing. That's probably the correct interpretation, yes. Nonetheless, the "card effect" comes from Return to Rhosgobel, not the Athelas cards (these have no effect at all). It's just poor wording, I guess, but I thought I'd check.

Here's a question concerning the interaction between Wilyador and Return to Rhosgobel. Wilyador ability reads: Forced: At the end of each round, Wilyador suffers 2 damage. Wilyador cannot be healed of more then 5 wounds by a single card effect. If Wilyador leaves play, the players have lost the game. And Return to Rhosgobel 3b: When Revealed: Heal 5 wounds from Wilydor for each Athelas objective card the players control. By card text, it looks like you can only heal a maximum of 5 wounds on Wilyador, even if you control more than one Athelas card. Which would make the effect completely pointless and the quest unplayable, so I'm probably wrong... right?
