OK - this is a stupid question but to dual cast a spell do you just have to have the spell in both hands and cast from one or do you need to cast by pushing both mouse buttons at once?
Im not sure how it is with the mouse, but
on the ps3 Ive been putting the spell on
both triggers AND holding both down.. .
I havent messed with dual casting to much,
I usually run around with a one handed weap
in one hand and cast with the other hand.. .
