Ok, well since you're set on kabuff, which i think is fine, would you be willing to at least just make the mention of zap as an alternate idea?
I think heal could also work instead of kabuff since both would make erdrick's stock last longer. And balanced out it wouldnt have to be overly good. Anyway, it's ok not to have heal in there, it would just be interesting because no other character except wii fit have a heal. Ill think about it for if ever i do another moveset, but really after yours im not sure there's a need for me to make any other, maybe just an addendum or something. Cuz besides what i talked about i would only mention changing like 2 ground sword attacks to be something else and that's about it ;p
The hero class is not really a support class, so I just think having zap as an option would really shift everything into place. As a jack-of-all-trades you could say, having 2 support spells and 2 offensive spells would be perfect, lol. Because I actually really love the short menu with only 3 spells to choose from, it really makes it simple and would work. Seeing zap in there would feel more canon to erdrick since he can't use any of those spells in dq3 and i think neutral b, along with seeing a menu, would feel good to see it in there
Did you give a shout out to the erdrick thread in there (for inspiration or else)? If you do and add even just the mention of the zap idea, I would share the document with basically anyone, dq fan or not. It's probably one of the best character movesets ever XD
