Husk outpost.

I was thinking of a desert structure made out of sandstone or something like that, where husks can spawn with any armor and weapon of choice, similar to the pillager outpost, but instead of an army of illagers, it's an army of the undead, and once you defeat all the husks there's a chance you could find the necromancer staff, a new item that has a chance of spawning in the chests, this item can raise a small army of the undead, and to make sure it's balanced it only has a 1 in 10 chance of spawning.
