I came up with this little variant, based off of the spell less paladin and ranger.

Variant Martial Hex: No spell casting or familiar;
-gains Fast Movement (Ex) at 6th level;
-gains a supernatural ability that grants +4 to a pertinent ability for 1min/class level usable once a day at 11th level;
-Improved Mettle (Ex) at 13th level;
-Camouflage (Ex) or Hide In Plain Sight (Ex) at 16th level;
-and bonus feats may be drawn from the fighter bonus feat list. SU abilities use class level as caster level.
-Use Magic Device is a class skill.

I originally thought this up for a character who was a kind of caster-killer. Gimme any opinions you have.
