So I added a bunch of monster abilities to the unused skillset #50 including triple breath, leaf dance, wave around, thundersoul etc. I filled the skillset and everything seems to work without glitches
Thought I'd mention this because I've seen it mentioned around that monster abilities look buggy on humans.
They're not always set to animations that match standard spell casting on humans. And from my experience with event editing (and having early attempts reviewed by far more experienced eventers) I can say it's easy to miss something that sticks out like a sore thumb to others if you're not quite sure what to look for.
What I did was used 1ability from every monster family.
So one Chocobo ability
One cat ability
One bomb ability etc.
Conveniently there are just enough still slots to use 1 ability from every beast type ;)
I mean some of the cast animations look silly but I was expecting the sprite to fall apart from what people had been saying.
The end result was in fact a very usable job that doesn't have any serious hiccup in animation. I'll try to post a video or something or you can check it out when I release the beta for the patch sometime today hopefully.
