Qinggong Monk spells depending on Int or Cha

[Zen79]

The Qinggong Monk has several spells on his list which depend on Int or Cha, for example discordant blast computes a CMB based on Cha, and strangling hair makes a grapple check based on Cha (if you are a sorceror) or Int (if you are a wizard).

My question: is it intended that the monk uses Wis instead in these (and other) cases?

Well being that...

A qinggong monk’s class level

is the caster level for these spell-like abilities,
and she uses Wisdom to determine her concentration check bonus.

The saving throw against a monk’s ki power, if any, is equal
to 10 + 1/2 the monk’s level + the monk’s Wisdom bonus.

I think that's enough to prove to me that he would use his Wisdom for those spells.

I agree.

It may not come right out and say so, but it's a safe bet you should use the same stat for misc. stuff as you use to determine the DC, which for the Qinggong monk is Wis.
