How it works
The strike still lands by number, but blank faces build a Void pool. Each element converts that pool differently: Agni burns it for damage, Jal turns it into defense, Vayu trades it for hand cycling, and Prithvi banks it while keeping cards in play.
Legend
Blank number: Void +1 and draw 1.
Blank element: Void +1.
Agni: spend all Void for +2 damage each.
Jal: convert Void to 2 Block each.
Vayu: spend 1 Void to return the fired card to hand.
Prithvi: keep the fired card on the board and gain Void +1.
Akasha: wipe the pool and all occupied slots fire at half.
