Undying Sigil
Enemies with at least as much Doom as HP deal 50% less damage.
Undying Sigil is a situational relic whose value depends on whether your current build can actually convert its effect into fight-winning tempo, scaling, or consistency.
Best for players whose current deck already benefits from doom, or who need this relic to make a draft direction feel more coherent.
Treating Undying Sigil as generic value instead of asking whether your current build can actually convert it into tempo, scaling, survivability, or consistency.
In Slay the Spire 2 Early Access, relics are often more important than they look because they do not just add raw stats — they can reinforce a draft direction, fix weak openings, or turn a shaky build into a real plan.
That means the right question is usually not “is this relic strong?” but “does this relic make my current build stronger, smoother, or more reliable?” Pages like this are meant to answer that second question.
