Honestly mate.. i wouldnt even make a obby pure.. yeh b4.. they wer good.. but now evryone is one... + u need to spend 3m - 3.6m on the zerker neckless.. and since theres so many obby maulers.. other pures safe against u..
I would train at the goblins lvl 13 under barbarians for now i guess..
When you get higher lvl just move further in there and face the higher lvl monsters
