Lava Lamp is a Shop relic that upgrades the card reward if you took no damage during that combat. The no-damage clear is an extremely stiff condition and actually fires only in narrow windows. Some early weak-mob fights will clear it, but Elite and Boss fights are effectively impossible to no-damage. The relic only becomes valuable once a strong defensive deck is already online, and by then card upgrades have lost most of their meaning.
