Question about abilities that debuff

[pufflesmash]

Telekinetic Smash is a mind ability that deals weapon damage and stuns. The damage obviously scales with mindpower, but does the chance to stun increase with p.power or m.power, and does it roll against p.defense or m.defense? Sorry if this is a stupid question.

it, seems to be based on Mind Power, if i am reading it right.
if hit and target:canBe("stun") then
target:setEffect(target.EFF_STUNNED, t.duration(self,t), {apply_power=self:combatMindpower()})
