Relic effect

Whenever you play 2 or fewer cards in a turn, take half damage from enemies.

Run value

Evaluate Diamond Diadem by when it appears, how often its effect triggers before the next boss, and whether it changes routing or shop priorities. The strongest relic is often the one that solves the deck's immediate weakness, not the one with the highest theoretical ceiling.
