[Monster Manual III had a number of monsters that were variants of core creatures. The salt mummy is my favorite because salt mummies are, you know, real. Although the real ones tend not to try to beat you to death.]
Salt Mummy A withered humanoid shambles forth, its body
desiccated and studded with glittering white crystals. Its jaw gapes open
slackly, but its eyes are filled with malice, and it reaches forth with
grasping hands.
Salt mummies are
the preserved corpses of humanoids dehydrated by exposure to salt deposits.
Although many bodies can become preserved in this fashion, only those that died
with some unfinished business become salt mummies. Their restless souls remain
held in their bodies by a desire for revenge, now expanded vaguely to include
all living humanoids. They are stupid, recklessly violent creatures in their
natural state, carrying on subterranean rampages that end only when they are
slain or run out of victims. Some necromancers seek to control or create them,
favoring their toughness and single-minded dedication.
A salt mummy can
be made using a create undead spell
at caster level 15th. The body must be packed in salt and allowed to
dry for a year and a day before it is suitable for animation as a salt mummy.
Salt mummies are found in the barren wastes of Koll’s northern desert, where nomad tribes use exile in such environments as a punishment for capital offenses.
