Fargo's Mod/Phantasmal Leash of Cthulhu

The Phantasmal Leash of Cthulhu is a craftable post-Moon Lord endgame flail and is the final upgrade to the. On enemy hit, it summons 8 Phantasmal Spheres around the flail that home onto the nearest enemy, a ring of Phantasmal Eyes that are sent outwards from the flail, and a swarm of fast Phantasmal Eyes from off-screen that home onto the nearest enemy. Phantasmal Eyes cause a Phantasmal Blast on enemy hits, which deal substantial damage to any enemy near it. These effects except for the swarm of Phantasmal Eyes are also triggered as soon as the flail turns to the "returning" state.

As it is a 'launched' flail rather than a 'thrown' one, it cannot be flailed around as you walk, immediately disappearing upon its return.

Its best modifier is Godly.

Trivia

 * The weapon's base damage is the same number as the Eye of Cthulhu's base health in Normal mode.
