6 armor buff, 5 heal, 4 light, 3 fire, 1 frost. alternatively you can use 2 light/5 fire if you're more kite oriented. imo, just keep practicing til you can master 10m range on fire and rock the 4 light. the debuff on light stacks like three times i believe? (maybe four?), you can cast it every 3 seconds, and the dmg is pretty damn good. also, i'd ditch all weapons and other than paw and throw on alch during mage duels or if the duel is going on longer than it should and you need some mana regen. and if you have enough plat then keep buying the rhino packs until you have a full guru set (not the armor that is black). i feel like having a full guru set is integral to the 20-22 str mage.
