The Vaporizer

The Vaporizer is a very difficult post-Moon Lord boss. It can be spawned after defeating the Phantom and the world has entered Epilogue, defeating it will revert the world back to hardmode. The only guaranteed drop is the powerful Vaporsword. It looks like the Spirit Of Might but it is not a worm (meaning it only has its head) and the blue veins are of different colors. The inner mouth holds 2 blue tentacles extending from its tips.
