Veridian Mod/Devil's Pendant

The Devil's Pendant is a Hardmode with a 1/5 (20%) / 1/4 (25%) chance to be dropped by Wall of Flesh. It gives +4% damage and critical strike buffs and a chance to increase life regeneration when taking damage. Its stat boosts are further increased to +8% if the player is currently in the Underworld. It has a chance to grant the player a sizable regeneration buff upon taking damage.

Trivia

 * This item's sprite and effects are loosely based on the Pentagram item from The Binding of Isaac: Rebirth. In that game, the Pentagram is a devil item that increases damage by +1 and increases devil deal chance by 12.5% (though the game lists it as 10%), the same chance of Devil's Pendant granting life regeneration.
