rune plate and legs, berserker helm (fremmnik trials is easy, did it at like lvl 70), get a cb brace or d gaunts if ya want def, a d long till you can use/afford whip (hits better for training), d boots asap, rune defender if your def is good but i suggest an obby shield till like 70-75 def, and a glory.
with that you should be good, oh and not to mention an obby or mage arena cape!!!! (60 mage req for mage arena tho)
