Du'ulora Ancestor
( Player's Guide to Eberron, p. 83)[Racial]
The tsucora are the most common of the quori, but they are not the only spirits in Dal Quor. You are descended from a du'ulora quori--a spirit that feeds on human anger and rage. By drawing on your du'ulora essence, you can enter a state of focused fury.
Prerequisite
CON 13, 1st level only, Kalashtar,
Benefit
If you have the rage class feature, you can expend your psionic focus when you enter a rage to extend the duration by 5 rounds. If you are a multiclass character, your barbarian class level does not count when determining whether you take an XP penalty.
