From 1-55 I just cast the spell that you could do at the level on a lesser demon in wizzards tower great exp because, it's like level 83 and it can't attack you. 55-80 i did alching which cost me around 20m, and 80-90 i made air orbs which i made 25m off that so i made back the cash that i spen from 55-80 then, 90-99 i cast string jewerly lunar spellbook it cost me 30m with all the supplies i needed.
