I find a Ninja with Bare Handed and the floating boots is excellent, especially if Move + can be added also, and punch art as a secondary ability. He usually gets the first turn, has great distance travelling and deals around 170 damage+ from each turn, totalling over 340+ damage if both hits land. And if he can't reach em, Earth Slash or Wave Fist can do the job.

Agrias as a Priest with equip sword works for me too.
