i think ice/light would be best because then you get the grasswalk and stuff but you miss out on imune = ( but id go with fire if you dont mind running slow or buying heeps of drugs
you wont really need ice at 80. sure it helps, but fire spear and imo light are way more important. im hybrid spear and im doing 80 spear 80 fire 80 light 60 ice. ice to 60 because of the passive. it helps a lot. plus at that level you can get the last book of snow shield.
what do you plan on keeping your magic balance at?
