I used a dusk ghostly elixer and i dont know how to change him back or into something similar. My pets a kumos.

You have to buy another elixir in the color and species you want.

Where besides the magic shop can i find the elixers?

User shops. You can search for the one you want through shop search.

okay thank you i found one and i hope id do no more damage lol

No problem. Welcome to Subeta, by the way!
