Turnip

Turnip is a rare relic that makes you completely immune to the Frail debuff. Frail reduces the effectiveness of all Block-generating cards by 25% while active. With Turnip, any Frail application is fully negated, meaning Block cards always work at full efficiency.

Frail immunity is most valuable in block-dependent defensive builds where Frail can be catastrophic. If your defense relies heavily on Block cards each turn, a single Frail application can leave you taking substantially more damage. Turnip eliminates that vulnerability entirely. It is particularly strong against specific enemies that heavily apply Frail and in Act 1 against the Jaw Worm. In builds that don't rely on Block cards, Turnip's protection is less meaningful. Note that Ginger provides the same Frail immunity; having both is redundant.
