How do you you become a wizzard ice lighting in maple story

First you must become level 8 and go see Grendel the really old in Ellinia (very top portal) then speak with him and he makes you a magician. After that, you must become level 30 and go speak with him again. After you speak with him, go to the map called "The Forest North of Ellinia" which is the top left portal of ellinia, then you keep going through the portals (two maps after the first one). Climb up the map until you see an NPC (no, not the cat). That is the NPC you are looking for. Follow his directions and you'll become a wizard in no time! :)
