Cross Necklace

Extended invulnerability and cavern Mimic drops

Obtained as a rare 16.67% drop from Mimic enemies encountered in the Cavern layer, the Cross Necklace alters defensive survivability. When taking damage from enemy hits or hazards, it doubles the player's invulnerability duration from 0.67 seconds up to 1.33 seconds. This extended immunity window prevents rapid burst damage during dense encounters. At the Tinkerer's Workshop, it combines with Star Cloak to create Star Veil, or crafts into Seraph Necklace and Crossed Heart Necklace.

Defensive value in boss fights and optimal reforges

The prolonged recovery window shines during intense boss battles like mechanical worm fights, where overlapping projectile swarms or repeated collision hitboxes would otherwise rapidly deplete health. While it does not reduce baseline damage numbers like Frozen Shield, it provides reliable safety against chain attacks. Players aiming for maximum defense should reforge it to Warding for +4 defense, whereas offensive combatants can choose Menacing to gain +4% damage without sacrificing the defensive perk.

Trivia

• The extended invulnerability frames do not apply to continuous damage ticks caused by contact with lava.
