World The Shifting Temple

Credit to @Bixlo for the idea
So, at night, a temple will appear near the Vandal lair. This temple would have a randomly generated labyrinth, filled with pot rooms and tier III and IV chests. However, if you make it to the deepest part of the temple, you are able to fight a miniboss named the Buried Necromancer. Killing him gives you a Sun Amulet, which you can give to the ancient merchant in Almuj for powerful, Egyptian myth based weapons.
The tomb has 3 floors, and the deeper you go the more hell like it looks like. Ancient soldiers, mummified wizards, hellish scarabs, and more stray through the halls, there to kill anybody who dares invade.
