Let's see if I can decode.
"Magic is powerful" -Stating the obvious.
"you can take life and i have" -I believe this refers to murder, which is most likely not true since, if it were, the person would either be caught already or smart enough not to brag on the internet.
"15 years of this i love it" -Claiming 15 years of experience, which is probably inaccurate based on the previous statement and the last.
"the biggest goal my sprits" -This either refers to working with spirits in which case the poster wants to learn to communicate and cooperate with them or this refers to his/her own spirit in which case it might mean spiritual growth.
"im the one you call on if you have a littie proplem" -I believe he/she meant 'little' which may be all he/she is capable of if that. Could mean if someone is bothering you he/she can take care of it, based on the second statement.
"im a grand dul inperele waizerd" -I think he/she is claiming to be an 'imperial wizard,' a claim of status that doesn't exist and if it does it won't be recognized here.
My guess, based on all evidence provided, is this person believes this site is for roleplay.
