If a 17th level character channels say meteor swarm through the Guardian angel it will gain 9d6 damage correct? That is fine, +9d6 to a meteor swarm isn't overpowered at all.
However, in the same round 150 level 1 wizards (Gained from leadership or whatever) can cast magic missile and ALSO gain +9d6 damage. I feel that in this case the wizards casting magic missile should get an additional +1d6 damage.
Does that make sense? Or am I misinterpreting something?
