Mental Turmoil

You set a mental barrier in the target's mind, preventing it from using abilities that require mental calm. While under the effect of this power, the target cannot use any Charisma-, Dexterity-, or Intelligence-based skills (except for Balance, Escape Artist, Intimidate, and Ride), the Concentration skill, or any abilities that require patience or concentration. In addition, the target can't cast spells, manifest powers, user spell-like or psi-like abilities, or active magic items that require a command word, a spell trigger (such as a wand), or spell completion (such as a scroll) to function. The target can use any feat it has except Combat Expertise, item creation feats, metamagic feats, and metapsionic feats.

Augment

For every 2 additional power points you spend, the power's save DC increases by 1 and the power can affect an additional target. Any additional target must be within 15 feet of another target of the power.
