Not sure if anyone has done any science of these weapons, but my master ice staff charges go down insanely fast, at times I have to charge it in less than an hour.
I was wondering what actually happens if it runs out of charge? The enchant gives 3 things. Max Magic around 1.1k, reduce cost of cold touch and roughly 600 extra damage for cold touch. I can test the Max Magic the next time it runs out of charge to see if it reduces it, but as I'm on PS4 I cant test the damage or magic cost. Also, what would be draining the staff? I spam both cold touch and light attacks (for ultimate) so unsure.
