Yeah, I thought this was needed.
First off, the character you want to submit for Brawlers must be of Final Fantasy origin, or your own FFO character. You must provide the icon in the format that is attached to this post. For any skills that character has, name the icon state in the icon to the skill name. Also, skills must be set up like so:
Skill Name-Skill Effect-Mana Cost
Also, state any requirements for the character to be unlocked (Kill amount, death amount, point amount, defeat a boss)
As for any specific graphic effects for their skills, just tag it in with the icon and put it as "skillname effect".
Also, when submitting characters, make a new topic in the subforum for them.
