I lied, a couple more questions:
1) When the engulf card is played by a specter and I decided to play the wind card, can I still discard the wind card to avoid the damage? Also is it mandatory to do one of the actions listed if possible, or can you choose to just take the 5 damage?
2) For the revenant archetype, do I discard the card I played or does it go back into my hand when I lose all my HP and have to use the ability?
1) Hm, good point..and something I didn't clarify in the rulebook, so good find. Honestly, play it however you want, it won't wreck the game if you discard the wind in play or don't. Personally, I would allow the wind to be discarded.
And yes, you can opt to just take 5 DMG, but that would typically be less desirable than the other options given.
2) It gets deactivated if you die. That a general rule of thumb for anyone that I didn't make clear enough in the rulebook.
