yes, quite simple, but as we all know there are no stupid questions, just stupid people (just messing with ya) well it works like so...... first you get yourself the runes for the curse spell (body runes, earth staff and water runes or mud staff) then get a full set of metal armour, the best dragon vamps you can wear, metal boots, anything to get your magic bonus down then you just cast curse on something, and you'll fail it.... so you try again... it failed.... so keep trying until eventually your out of runes and have failed to cast the spell once, but dont worry! because you get the same exp for failing it as for casting it well! so you get the same exp and can keep cursing the same npc over and over again!
