Someone already made a post about a world called Avalon. Demon Lord? I guess it's okay. There's already a Gobbler treasure spell so making a normal one would be a waste, and it's under powered. Piranhas? Seriously? It's too unoriginal. Healthy Treant? That's the same thing as Treant, Life wouldn't be too happy to see that as a spell. Dark Sun? Eh..... Unoriginal and overpowered.
