ok, bit deatil? As in, Adding Enemies or Making them? ?_? if it's Making them, simply head to the database, Monsters, add/choos the monster picture by clicking the Blue Window, choose the Monster (Case the people) and add them by clicking on it two times, and customize it, click below were it says attack, and add skills and stuff.
If it's adding it to battle simply go to the next page of where monster data is...
There lies the group, make a new one, and here's a Small list on the right with all the monsters made, just click the bitton add and so on...limit are 8 Monsters =/
lol, Then again I didn't understood well xD
