Walking Beyond the Gate (3.5e Sacrifice)

The undead are but living warped, souls who has passed through the gate, yet their gate continues to function, open, pulling energy to animate the body. With that the secrets of undeath are open, allowing you to duplicate the effects of Animate Dead. You may animate a body free of cost, but the body will only last 1 round/level before the gate, out of control, sucks the body dry as fuel and disintegrates the corpse. By applying the material components, however, a permanent undead following all normal rules for the spell can be created.

Health Cost: -3 per undead created.

Material Cost (Permanent): Usual 25 gp per HD.
