Self-Forming Clay

Self-Forming Clay

UncommonIronclad
Whenever you lose HP in combat, gain 3 Block next turn.
  • Damage through Block: whenever you take damage in combat that gets through Block, you gain a stack of its power, 3 Block at the start of your next turn per instance.
  • Per hit: each hit counts separately, so a three-hit attack that connects gives 9.
  • Self-damage counts too: because Bloodletting and its kin deal unblockable damage rather than plain HP loss.
  • Ironclad only, Uncommon, 225 Gold, unlocked by the Snuffed epoch.

When to take Self-Forming Clay

Take it in a self-damage deck, where you control the trigger and turn HP loss into Block every turn. Otherwise it is a consolation prize for turns you already failed to block.
