75+ Strength
75 strength is a good start, but any higher would be better!
40Def - 30 Quested
If you get more than 32 def before doing your F2P quests you'll go over 40 def and we dont want that on a F2P Rune pure so 32Def max! if you haven't got Dragon slayer done!
59-70Mage
Fire blast is always nice and teliports
40-85Range
Running from mages with D'hide body , or Ranging noobs either or
Prayer 1 Or 31 or 43- If you get 31 thats 2 Cb levels and if you get 43 for Melee protect thats 4 levels, Its really up to you, prayer isnt Req but atleast 31 is advised
So with
40att
75str
40def
70Hp
59Magic
43Prayer
75Range
You'd be level 69 Which is pretty sweet and 85 str you'd be level 74 Good Luck!
