Hey I've been trying the game and it's quite a fun little fan project so kudos to you. I'm unsure so much if it's a bug but with Onion Knights Multi Hit command, I can't seem to make the synergy after using Element Charge but also when it times out it makes the next usable character perform an attack action (I haven't tried queuing a magic action so I'll look at that and test that for you also)

Interesting, that's something I wouldn't have noticed. So I'll give a few tries with OK and see if I can get it to fail. OK should function as so. "If there are any elemental effects (burning, frozen, winded, shock, etc). Then his multi-hit command should toggle, performing a 6 Hit combo." I also believe he gives you a Crystal Limit + too.
Thanks for the input, def gonna give this a shot later
