basically the first line is your 25 first lvl, after you got a bit and spam, afeter spam won,t work anymore and you stale. than discover block, mastering block, than staling... than discover chamber and feint and boom!!
not a relevant graphic, but my main advice is DON'T PLAY RAMBO, stay with mob and learn, after you'll be good and wealthy and you can enjoy crpg at is true valour!!
(ps don't go arhcer in first built as you won't learn how to block, hard way of pole is faster)
