The Stars Above adds 6 unique bosses to Terraria, all of which being in Hardmode. As 5 of the 6 bosses require The Vagrant of Space and Time to be defeated, it is highly recommended to fight him immediately after the Wall of Flesh has been defeated.
If the Calamity Mod is loaded, the bosses from The Stars Above have increased stats.
The Vagrant of Space and Time is an interstellar deity that actually doesn't have any hp at all and is instead a survival fight that lasts a little over 2 minutes. It is summoned anywhere, anytime on the surface with The Shattered Disk.
Penthesilea, the Witch of Ink is a witch who has mastered the art of... art magic with ???,??? (166,000) hp. She is summoned anywhere, anytime on the surface with The Unsullied Canvas.
The Warrior Of Light is a knight obsessed with the power of light with ???,??? (485,000) hp. He is summoned anywhere, anytime on the surface by using The Progenitor's Wish.
Tsukiyomi is the First Starfarer and the Progeny of Salvation with a total of ???,??? (775,000) hp. She is summoned using a Mnemonic Sigil at The Dying Citadel.
