its really easy to get impossible but it takes time.. lol, i think we really need a lot of more bosses after the corruptor cuz it becomes really repetative afterwards
darn i got all the badges except the impossible im only at level 28 but its halfway there ^^ the best build is 1 warrior quick build , 1 warrior tanker endure build, 1 ranger spear w/ full strength build(at the back) & and 1 ranger w/ a bow full dex at the back
