Revelation - If you are at an Extradimensional location, discard it and take 1 damage. Otherwise, take 2 damage.

My question is - can you choose to take the 2 damage if you are at an Extradimensional location, rather than discard it? I'd say no - it seems like a pretty straightforward if-then-else to me. But I've seen it played both ways.

There is no choice in this card.

Cheers, that's what I thought.
