I would say train your magic defense at the mine. Just let the goblins hit you, since they are so weak, and slowly your resistance to spells should increase. Also, lure two other goblins in and you also increase dodging and endurance. If you find yourself low on life (Which you shouldn't because they dont do much damage) try healing yourself. This is about the easiest way i know. if anybody else knows a better way, feel free to post.
