I made a post the other day about rune spells not benefiting from the perks that increase spell damage in the destro tree and learned to my dismay that they do not. But, do they benefit from the dual casting perk, would they be more powerful if dual casted? I dont want to use the perks unless i am certain one way or the other.
I've never been able to duel cast/set two runes on the ground. as soon as I cast a second one the first vanished... tried to fire and ice a pathway once... sadly no success.
