uhhh...? mazzle works for every and all characters. the min level is level 1 and the max level is whatever blizzard has it at and if mazzle is still working then.
what told you there was a min. level? and what level did it tell you?
nothing bisids the screen shots that i have found its just all the screen shots are with lvl70's so you rely cant tell if it works with the low lvl's from the screen shots
