Ancient Vision

The Ancient Vision is a Hardmode, post-Golem enemy that can spawn during the Lunatic Cultist boss encounter. It is only summoned if a player attacks a duplicate of the Lunatic Cultist while a Phantasm Dragon is still alive.

Trivia
It is a reference to Cthulhu with the Ancient Vision being nearly identical to his head. The Ancient Vision refers to hundreds of generations of cultists attempting to summon him.
 * It resembles the Moon Lord's head, but is not nearly as dangerous.
