It's... honestly hard to say.
You can't get in via Bard until late, but you can get in with Sorcerer at 8th level (Has to be spontaneous arcane), which still feels weird vis a vis the prerequisites (Perform 6 is higher than the cross-class cap at 8th, after all.)
I guess it's for Sorcerer, then? With maybe a dip into Bard for the ranks of Perform?
