Dungeon Crawl Classics has always needed a Succubus.

For Dungeon Crawl Classics, D20 compatible or #OSR games.
(Different artwork coming eventually.)
Natural form: This Type IV Demon stands between 4′ and 6′ tall. Typically has red or dark pink skin. Usually scantily clad in leather or chain mail. Has long hair, horns, batlike wings, a barbed tail, and hooves. Most often carries a whip and a length of chain and/or manacles. Beware, these creatures are not to be taken lightly.
Succubus (type IV demon): Init +6; Atk Whip +12 melee (dmg 1d6+6 or *entangle Reach 10′) or Claw +12 melee (3d8+6 damage) or bite +16 melee (1d12+4 plus Drain Blood); AC 22; HD 10d12; MV 60’ or Fly 40’; Act 2d20; SP spells (+8 spell check): detect good, Charm or scare, Shape Change, demon traits; SV Fort +12, Ref +10, Will +12; AL C.
*Instead of doing damage, the succubus may opt to entangle an opponent. On a successful hit, the Succubus may forego the damage and instead force the target to make a DC 20 Reflex Save. On a successful save, the target takes one point of damage. On a failed save, the target is entangled and unable to use the limb that was struck (Judge’s choice.)
Once entangled, the Succubus will begin to drag the target toward her at the rage of 5′ per turn. Once in range, the Succubus will attempt to charm and then bite the target and Drain Blood. If a creature breaks free, the Succubus will attempt to use her claws on the target until it is too wounded and must submit.
These creatures are extremely sadistic. They often toy with their prey, wearing them down slowly before going in for the kill. They may change shape at will to appear to be whatever race/gender is most appealing to its target. Succubi are lone hunters who prefer to seduce and drain a target rather than confront anyone directly.
