well, with veracs you need 70 def to wear (obviously) but i would maybe suggest getting 80 combat stats, so 80 atk, str, and def, then you should be able to do it very effectively and slayer dart is not affected mby negative magic bonus, so you can mage in your melee armur. If you do all this, you should get quite a few runs, although guthans would be better, veracus is second best
