Hm.. Has anyone tried it out in Goldor fight? It could maaaaaybe be useful in second phase adds attack, if that's all mixed.. but that already has safe spots, so it's not like it's entirely necessary.

Otherwise, yeah, there's little to no real use case for it. That said, historical-BLU is no stranger to "why would I use this?" spells. I'm not completely against the idea of it.. but, wouldn't ever slot it unless I'm doing something weird and have extra room for it.

I suppose, arguably, its existence might be justified by speed-runner types, that might want to absolutely minmax optimization. The sorts of people that will absolutely gamble on the skill make-or-breaking a run just to squeeze out some better DPS and show off a new record or something.
