can't target Heal. moved closer - still can't. next turn - got Minor Heal and another Frenzy, used Minor Heal, then was able to use Heal.
Looks you have Taunt attached. Wasn't aware this stopped targetting someone else for heals - but apparently it does. According to the card text, you're only allowed to target the owner of the taunt - so probably works as intended.
Definitely keep this thread for future info Could be a great multiplayer use of taunt vs enemy priests, if it gets added on items in the future.
