Undying Sigil
ShopNecrobinder
Enemies with at least as much Doom as HP deal 50% less damage.
Any attack aimed at you by an enemy whose Doom is at least its current HP is multiplied by 0.5.- Applies only to enemy attacks, after the enemy's Strength and other modifiers.
Doom kills such an enemy at the end of its turn anyway, so the relic covers the one attack it gets between passing the threshold and dying.
A leftover code comment describes an older version where doomed enemies died before acting. The shipped relic only halves the damage.
When to take Undying Sigil
Buy it when your deck can push an enemy's Doom past its HP a turn early, since that is the only turn the halved damage matters.
