[DF] Contemplating a Chi Mastery house rule

[PK]

EDIT: I decided to go with three custom power-up Talents that improve everything except DX-based skills. Thanks for the suggestions and opinions!


---Original Post---

One thing that we've noticed in our games is that the martial artist's esoteric skills come out very unbalanced if they take a mix of attributes. The DX-based skills are all in the 17-18 range, while the IQ and Per ones are 10-11. I'd like to find a way to address this without forcing them to buy up IQ, though I don't mind as much if they have to buy up Will and Per (since those are both cheaper and appropriately thematic for warrior monks).

So I've been contemplating this house rule, and am looking for feedback. It swaps bonuses on a roughly equal number of skills. I'm not sure if it's too powerful, though, even if it's explicitly restricted to Dungeon Fantasy.

Chi Mastery comes in two forms

In Dungeon Fantasy (and only in that setting), martial artists may take normal Chi Mastery or a new variant, Chi Mastery (Mental). The latter gives no bonus to DX-based chi skills, but gives double the bonus to IQ-based ones. There is no change for HT-, Will-, and Per-based skills.
