I have a lvl 77 (1:7 int) Hybrid. With heuk, light and cold @ lvl 72 (farming) and it is great though but 2 bad i cannot bring fire as well coz the physical fire buff is 1337. If you are going more in PvE take fire, light, heuk. PvP i would take ice, light, heuk. And if you are going 100% int then i would take ice,cold,fire. This way you can switch between spear and sword. Need more defense take sword shield out need more attack power take ur spear
