Whenever you play a card with an effect that deals arcane damage, you may pay [Resource]. If you do, that effect deals that much arcane damage plus 1 and at the beginning of the end phase, destroy Metacarpus Node.

**Arcane Barrier 1** *(If your hero would be dealt arcane damage, you may pay [Resource] instead. If you do, prevent 1 arcane damage that source would deal.)*
