When in a battle the enemy used a area of effect heal card that heals all targets around 3 squares. the heal triggered the block I had in my hand so not only I lost my block card I also didn't get healed. I don't think that's supposed to be that way is it?
It works like this: Abilities from allies do not trigger Blocks. Abilities from enemies trigger Blocks. After all, your enemy has no way of knowing if you're being a kind and caring enemy (?) or if you're trying to kill it with a lethal Misguided Heal. This is on-purpose and great fun to use.
