Skeletron Ultimate

This is just an idea, so I dont really have much info about stats, drops etc.

Skeletron Ultimate

To be summoned, the following must be complete

Skeletron, Skeletron Prime, Plantera, and Ocram must be defeated. One biome chest must be opened. During blood moon.

To create him, 5 pieces of him must be made. Legs, Chest, Arms, Head, Soul. Each piece will be very small, roughly x1.5 bigger than the player. Pieces can be placed any time, but the whole thing will only summon Skeletron Ultimate during a blood moon. The Chest will appear to have a circular hole in the center, where the soul is placed.

Crafting:

Legs: 50 bone, 10 meteorite bars, 2 Souls Of Night

Chest: 70 bone, 30 meteorite bars, 10 Souls Of Night

Arms: 50 bone, 10 meteorite bars, 2 Souls of Night

Head: 30 bone, 10 hellstone bars, 5 Souls Of Blight

Soul: 5 of every excisting soul, Clothier Voodoo Doll

Skeletron Ultimate appears to have dark colored armor, with his eyes lit with fire. Skeletron Ultimate is armound x2 the size of the Golem.

Like I said, I have no idea for drops, stats, or a sprite.. Killing him will have a bigger effect on the clothier on blood moon, and not just change in dialogue and different sells.
