Ascetic Psion

( Secrets of Sarlona, p. 115)

[General]

You are a practitioner of one of the many styles comprising the kalashtar path of shadows, such as the Tashalatora. Mixing meditation, discipline, and movement have taught you to become psionically focused more easily while distracted.

Prerequisite

Improved Unarmed Strike (PH) , Narrow Mind (XPH) , WIS 13, manifester level 1st,

Benefit

You can become psionically focused as a standard action that doesn't provoke attacks of opportunity.

If you have levels in psion and monk, those levels stack for the purpose of determining your AC bonus. For example, a kalashtar 4th-level psion/1st-level monk would have a +1 bonus to AC as if he were a 5th-level monk. If you would be allowed to add your Wisdom bonus to AC (such as for an unarmored/unencumbered monk), you can instead add your Intelligence bonus to your AC.

In addition, you can multiclass freely between the psion and monk classes.
