Okay my pure is level 74 heres my stats, i eventually want to become a tank but i am unsure when to start training def. I also would like to know when and IF ishould get 45 def. It will be greatly help full
Personally I love zerker pures. 99 strength, 75 attack, 45 defence, 94 magic, 99 ranged and 44 prayer. You could still be able to get that.
Anyhow if you want a tanker, I think you shouldn't train your strength or attack (maybe attack to 60) any more. Just train defence and ranged.
Don't train any def until you have barrows gloves. Also, get 60 attack, 80 strength, 85 range, 70 mage and 52 prayer. Eventually you'll want 75+ attack, 90+ strength, and 94 mage but these things take time.
