Oops I drew another witchsona!
This is Fight Witch. My strongest magic is made by using the Blood of My Enemies, but it can only be collected while in the ring. Fortunately, I can create a magic circle anywhere, and that counts as a fighting ring.
My familiars are a group of large of black birds that surround the ring during the fight, just in case the other party tries to leave.
(See my other witch, Coffee Witch, here.)
