Cross Necklace

The Cross Necklace is a Hardmode accessory that doubles the duration of the invincibility a player is afforded after taking damage, from ~0.66 seconds to ~1.33 seconds. The Cross Necklace has a 14.29% (1/7) chance to be dropped by Mimics.

The Cross Necklace is useful in Hardmode boss fights, and any other scenario where the player is likely to be hit rapidly.

Tips

 * The Star Veil and Cross Necklace invincibility effects do not stack.
 * The Cross Necklace will stack with the Black Belt or Master Ninja Gear to extend the dodge invincibility period by 2/3 second to a full 2 seconds.
 * One can become invincible if they create an invincibility chamber using a Slime Statue and a Heart Statue wired to a 1 second timer in an enclosed room and wear a cross necklace. By having the Blue Slimes hit you constantly, the cross necklace gives you almost constant invincibility.
 * The invincibility is effective in PvP.

Trivia

 * This item may be a reference to the Cross Necklace in the first Castlevania game, having nearly the same image and making the player invincible for a short duration.
 * It bears resemblance to a Catholic.
