Clouds limits yeah, effected by Short/No charge. Archers "Charge", Lancers Jump, and MAYBE Dance/Sing are the things not effected by Short/No Charge.

I've never technically tried Sing/Dance with No Charge, but if it had no charge it would infinitely repeat over and over, unless Short/No charge simply made the initial cast time of it shorter (which isnt that long usually anyways)

Luckily Clouds Limits are considered a spell-based charge time
