With a Roar Animation, broken damage scaling allowing it to one shot players, and a need for clash visuals, I think Surge is a Continuous Fire Beam.
Think a Kamehameha, a beam that you fire nonstop for a few seconds thats meant to stack damage. Got no proof, but it would make sense. The only times damage breaks hard enough to kill people in one shot is on multihit spells. Surge as a name could fit this still, a ‘surge’ of magic in a continuous line. Then a roar animation could be something in line with Broly roaring his beam in Dragon Ball.
That would be absolutely sick, but I don’t think we’d get something like that. Or if we did, it wouldn’t really be an optimal or good move. Multi hits suck right now cause of how easily they can be punished, right? Or how hard they can whiff? Or am I just dumb?
If I had to guess though we are getting one spell for pure mages and one for hybrids, so… we might not be able to enjoy this. Well, I won’t be able to.
