Looks like you do not really understand the various terms so i guess i will explain it to you.
Wiccan~A term refering to a person who is a follower of the religion wicca , a polythestic religion .
Wizard~A path a practictioner follows where they learn forms of magic that attempts to control the surroundings. However , they do it in more gentler forms where they only alter the path of what has been set , not change it totally.
You are not following any of these paths yet , i assume so you shouldn't really be titling yourself as such.
"i found a cowardise spell online that can reverse your wizard powers."
Please rephrase your sentence..I have no inkling of what you are trying to say.
