What do you feel about monster companions/enemies
Like goblins, lizards, elves, dwarves?
Also, i'd suggest a returning rival, everytime you defeat her she gets stronger, like in a pokemon game, but this style
There is a Lizard Enemy currently in, And I can add in a goblin or two new enemies, Elves would be fine to add, but dwarves would be the cut off point for me, I am imaging Stable Diffusion having trouble with dwarves, unless I can find the right Model to use, Which I'd rather not spend too much time looking for a model to just make dwarves.
