hello,

i ve a question about spelling destruction spells.
almost everytime i fire the balls with the right and the left not the same in one time.
i pull both of the triggers but i shoot 2 firebals but i want 1 with 2 hands.
thanks

do you have the dual casting perk? if not you need that

You need the dual-casting talent for that.

But I wouldn't bother with it unless you get a mod that fixes dual casting or have armor that makes the spells essentially free. By default it's a lot less mana efficient, though you do damage a little bit faster.

You need the Destruction dual casting perk. This requires you to take the novice perk first.

thanks

It can be argued that casting with separate hands is more useful.
Instead of doing 220% damage for 280% magicka, you do 200% damage for 200% magicka and get a higher rate of fire.
