Cool, sounds good! You're welcome.
I forgot to say, I'm not sure if you use the same code for all knockback effects or not, but I think I saw that Ring Gust bug with another ability. I couldn't remember which units I was using that time though, so I could be wrong.
For the damage variance, could you just show the range? 7-9 damage, 12-14 damage, etc. Even if the chance isn't always even, at least then players would know the possibilities.
