(Complete Psionic, p. 60)You host a psionic entity that dislikes combat and provides you psi-like abilities to help you avoid a fight.
A psionic entity takes up residence within your flesh. The entity grants you the following psi-like ability: Psi-like Ability: 1/day--deaden blow (see page 82) or entangling ectoplasm. Manifester level 1/2 your HD; save DC 11 + your Cha, Int, or Wis modifier.
You can use one or the other of your entity-granted psi-like abilities once per day--you can't use both. Once you use one, you can't use the other for the rest of the day.
