I really like this build for glaivies: heuksal 110/ fire 110/ lightning 90/ cold 20.
From lightning try to lvl up piercing forse, thunder walk, concentration and heavens force series.
From cold: frost guard(does small amount of phy. def pwr), snow shield and cold armour series.
Dunno, about you, but I choose to lvl up cold just for snow shield. And I am not dissapointed at this point, cuz my glaiver does good damage and with snow shield you won't get 1-hitted by your lvl wiz.
Well, you can always lvl up all lightning for a good speed and parry ratio.
Well, this is the guide I followed:
