If Riff is fine with a one turn cooldown, then all of the other globals should also be changed to a one-turn cooldown.

What globals exist that don't already have an innate cooldown by way of just being invocations? Riff is 6M, not 9M, which is why a cooldown would be good to begin with. And even then, it still has a leg up on other globals when you do the math. While I'm all for small, incremental balance changes, I think Riff would still be too good with just the 1 turn cooldown. Make it 2, or cut the scaling a bit, or make it not global. Any of them would work, IMO.

EDIT: Ascended youkai came to mind after I asked that question, but the numbers on that aren't even comparable to Riff, so I don't think they need nearly the same treatment.

Enma's Summons, Divine Shower, and Unmasking Trail all have three round cooldowns that only start ticking once the cast is successful.
