Well for me, combo only for lvling @_@ .

Angela: Water element, can heal 1082 at max lvl, after reborn can heal up to 2k, AOE freeze, curse (-def? +atk?), but the atk.... (low?), more in support type.

Eva: Fire element, save money on weapon (it have critical in the fork), mess(90%), after reborn get better atk skill, another atk skill with 30% chances of abnormal aliment (freeze,sleep,terra,mess...?)

Now is ur time to headache =D
