In the expanded psionics handbook how does it handle psionics and undead? in 3.0 psionic attack modes bypassed the general undead immunity to ability damge.
from the srd:
UNDEAD PSIONIC CREATURES
Undead psionic creatures are rare. They can use psionic attack modes, but must also learn defense modes, since undead take ability damage from psionic attack modes.
An undead creature can use Psychokinesis powers, but it substitutes its Charisma ability score as the key modifier with these powers. An undead creature cannot use Psychometabolism powers, since it has no metabolism.
Undead are immune to mind-influencing effects, however psionic undead beings can still use mind-influencing powers on the living.
