Two things spring to mind, well sprung to mind when I was on the throne:
1. Just tack ranged martial arts onto ego blasts and away you go.
2. The other thought I had was only for mentalist v mentalist combat if you use the optional expanded rules. The block, dodge etc. If those rules are used and when in combat with another mentalist, could one be so skilled in this combat that he takes it to another level? In a similar way that a mental dodge gives you +3 decv a martial mental dodge would give you +5 decv.
Now, if you allowed this for a special villain or PC how would you cost it? The same as DYO martial arts? Or would you give a discount as it would have limited use unless v another mentalist?
I can see I'm gonna have to go back and have another look at the Ultimate Mentalist.
