What quest did you do to get pray up?
The pure is good but it lacks the basic skills you need to complete DT and it also has only 40 range and 43 mage.
Still 60 atk and 99 str is really good on a pure.
Also because of the new Combat Evolution people do not know what will become of pures.
Also no dung levels.
I would say 25m s/b and 40m a/w
But then again it is your account and if you take the time to sell it you could get more. Hope this helps.
