Kate uses daze on Renk, over-channeling to provide a boost for combat in the next round, even though the brute probably doesn't need it.
Spoiler: the breakdown
Daze cast at effective power 3 for 1 pp
(1d100)[28] need 11 or higher to avoid enervation
Either way, Renk suffers the effect of Psionic daze if he is 6HD or lower unless he succeds a DC 14 will save
