Your king cannot be captured for your opponent's next 2 turns. Every enemy piece that ends a move next to your king in that time is frozen for 1 turn and bonked where it stands.
You draft Frost Ward in Buff mode. Passive: it works on its own the whole time you hold it, with nothing to activate.
As a protection card, it shields a piece or bars squares from the opponent.
“A rime of protection, and it bites back.”
Affects your kings.
