Fargo's Mod/Ancient Shadow Enchantment

The Ancient Shadow Enchantment is a craftable Hardmode accessory.

It summons three shadow orbs that will surround the player. If one of them are shot, a spurt of homing shadow energy is released which will attack nearby enemies. Attacks have the chance to inflict the Darkness debuff. Debuffed enemies fire shadowflame tentacles at other nearby enemies, dealing damage and inflicting Shadowflame. It also summons a Shadow Orb pet.

It is themed after Ancient Shadow armor.

Trivia

 * The symbol on the Ancient Shadow Enchantment resembles a smashed Shadow Orb, similar to the "Smashing, Poppet!" achievement icon.
 * The shadowflame tentacles can also inflict the Darkness debuff, potentially causing an infinite chain reaction.
