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.

Behavior
The Ancient Vision's behavior is similar to that of Mothron's charge attack, as it flies quickly towards the player while leaving an afterimage behind it.

Trivia

 * The Moonling pet summoned by the Master Mode-exclusive item  Piece of Moon Squid, shares a silhouette resemblance to the Ancient Vision.
