I just noticed this annoying thing. Lets say you have two spells based on the same ability, for example acid bomb, and you cast them on the same target. What you'll get is the effect of the last spell that was casted but with duration equal to the longer one of the two spells. So you can first cast a spell that has a long duration but little damage and afterwards cast a spell with small duration but a lot of damage. The result will be a spell with a lot of damage and long duration...Any solutions on this?
