but you can hit him and heal, i don't recomend a double saber, dagger or mech to do it, but with a gun you can hit and heal, hit and heal over and over, as long you know how much damage you do, it's fine.
a tech is also a good thing, normally on non force chars the tech is weak so you can make some use of the tp to inflict damage and maybe kill him.
