Phantasm Dragon

The Phantasm Dragon is a Hardmode, post-Golem boss servant that spawns during the Lunatic Cultist boss fight. Its behavior and stats are nearly identical to the Wyvern's. The Lunatic Cultist summons a Phantasm Dragon each time the player attacks one of the Lunatic's duplicates. If the Lunatic Cultist completes the spell once more with a Phantasm Dragon still alive, it will summon an Ancient Vision instead.

Tips

 * Like all multi-segmented enemies, the Phantasm Dragon is vulnerable to weapons with piercing and area-of-effect damage. If the player has already defeated the Solar Pillar before, the Solar Eruption is available as an effective choice. Other options include the Electrosphere Launcher and the Toxic Flask.
 * Due to its large hitbox, it can be hit easily with Vampire Knives, which will restore a lot of health.
 * The player should try to aim for the Phantasm Dragon's head, which has the least defense out of all of its segments. However, it also inflicts the most damage.

Trivia

 * The Phantasm Dragon is a total of 30 segments long. Its first segment is the head, the other 29 segments consist of the legs every four segments (for a total of 6 legs), with the final three being the tail.
