Protector

NecrobinderAttackAncient
Osty deals 10 damage.
Deals additional damage equal to Osty's Max HP.

Osty swings once for 10 plus a bonus equal to his current Max HP. The attack is his, not yours: Calcify adds to it, your own Strength does not, and Vulnerable on the target still multiplies it. If Osty is dead or was never summoned the card does nothing and is still spent. The upgrade lifts the base to 15 and drops the cost to 0.
