Use killey, use double beats if you have them and fury runes too... on riou and killey, you already win;... kindness/friendship rune(I forget which, maybe either) on riou
if you need to supplement that; I like wakaba, Tengaar, Rina... I stay away from one hit powerhouses like Georg, peshmerga, Humphrey but they're fine if you can deal w misses... I also kind of avoid magic users w short range weapons but tbh I feel you always need one with a flowing, and rage/thunder/pale gate and wizard rune, and when you choose; the answer is Luc, not Mazus. ---
