Train for 1 gold
To train for 1 gold you must go to sadrith mora and in the dirty muriels club you should find the master of illusion (he is on the top floor in a green robe)
buy the 'scourge blade' spell to get drain skill
then go into spellmaking menu and make the spell drain 100 to 100 mudutide on self for 2sec (when you open the drain skill a menu should came up with all the skills click on the skill you want to increase) then go and find a trainer that has the skill you want cast the spell and quickly enter the training menu if u did it correctly the skill you picked should be on 1gold
when you train a messege should come up saying 'your .... has gone up to 0' dont worry about that when the spell go off your chosen skill has actully gone up by 1
