Concentrated Power

Starting at level 10, you have learned to focus your most powerful magics to single targets instead of multiple. When you cast a spell that damages multiple targets or a non specific number of targets in an area, you can instead tally the total damage dealt and apply it to one single target, for example, 20 points damage dealt to 5 separate targets caused by a fireball spell can instead become 100 points of damage dealt to one single target.
