Improved grab with the tail? "Gnaw", or whatever we called the ability that allows a free bite attack on a grappled foe?
PSYCHIC PANDEMONIUM: This psionic attack mode attacks exactly like a Mind Thrust, but it may only be defended against with Tower of Iron Will, and then takes double pts. from the defender.
Here's 3.5 mind thrust...
Mind Thrust
Telepathy [Mind-Affecting]
Level: Psion/wilder 1
Display: Auditory
Manifesting Time: 1 standard action
Range: Close (25 ft. + 5 ft./2 levels)
Target: One creature
Duration: Instantaneous
Saving Throw: Will negates
Power Resistance: Yes
Power Points: 1
You instantly deliver a massive assault on the thought pathways of any one creature, dealing 1d10 points of damage to it.
Augment: For every additional power point you spend, this power’s damage increases by 1d10 points. For each extra 2d10 points of damage, this power’s save DC increases by 1.
Tower of Iron Will now grants power resistance.
So should psychic pandemonium simply function as mind blast, with a greater chance of overcoming power resistance? Or should we make it a Su ability, similar to a mind flayer's mind blast, and make it similar (but slightly different) to mind thrust?
