I've been planning something like this for over a year, and adoptable that you can battle. I'm jumping into the deep end here, but this is a bit of a test for the battle system, if it works works I will continue with my bigger project :3
But for now, this is what these little critters are:
Magie sprites are nature spirits. They battle each other territory, with each battle they win, they get stronger.
Each sprite has their own line art and ability so each is unique, you can also buy items from the store to boost power and change appearances to customize even more.
You can choose what four attacks sprites have and change them whenever you like (just not in the middle of battle)
Sprites come in twelve different elements, fire, water, earth, air, ice, lightning, darkness, light, plant, animal, spirit and mind. I am working on a chart, but some are more powerful against others
