One other route I like is.. spiritual way and mentor spirit wise warrior or dragon slayer which gives leadership skill bonus.This cost reduction cannot be used multiple times if the power has multiple levels: the reduction applies to only one level,
You then use the discount for 3 cool resolve at 1.5 pp.
Drop Auth tone and get improved reflex 2 and buy a qi focus force 4. Won't be able to bind it yet but can choose much easier after chargen or wait. Either way cool resolve is much more universal and helps resist social. That said the spell is fine too to keep Auth tone as well I just don't trust it after background counts.
Your spell can then be any of your usual deflect instead of more combat sense if you like. But being extremely hard to hit is great too.
So Cool Resolve would cost 2.5pp as you can only discount the first level.
If you could discount Commanding Voice in addition it might be a thought- but Commanding Voice isn't in the list.
Magician's way allows any power except Imp Reflexes so I suppose I could discount Commanding Voice, Cool Resole and Astral Perception for a total of 1.5PP
Still, 20karma to squeeze in another 1.5pp is a tad expensive.
As far as background counts that is what the Heightened Concern is for- well, for Background Counts of 3 or less.
