Personally iv got 75 attack 75 def and working on 99 strength,
75 def so at least when you fight epic monsters or even just in general you can wear that epic shield.
The best f2p items that have never let me down are:
Iron ore
Pure & norm essence
In the end of the day i always find my self going back to these f2p items to merch.
As another tip, I use a program called "Advitica MerchStation" really useful has the ability to produce the up todate graphs...
This account is still a low cb lvl and is ready to be molded into a epic account of your choice! :D
The account is technically a strength pure regardless of how low it is but with such a low strength level you can turn the account into whatever you want it to be.
The bank is all geared up...
