There is really no reason to have higher than 255 durability as long as you have 5 Self Repair on the item. It's pretty rewarding to get one crafted and level it. What you need as a base axe is 40+ triple leech and a hit spell (Fireball/Lightning/MagicArrow preferred Dispel doesnt count) and then if you look on the boards, ive posted a couple ways to level a weapon, Basically for champing you can either go 2 hit areas/2 hit spells or one hit area/3 hit spells. Dont waste points on Lower attack or Defense, they are mildly useful in PvM but not worth wasting points on.
