does it player kill?

yes theres a bounty system

yeah u can pk with bounty or go to the PvP areas which are mudo island and tranquil vale (sometimes difficult to get a 1v1 fight in these 2 areas) if ur fightin with friends just use bounty

yeah u can pvp with other player .just use bounty to kill but it cost the gold u have to pay in 350k and u will get back in 250k.100 k is for tax. if u pvp ur friend just turn on ur bounty ^^

There's bounty system where you can earn from 250k to over 64 mil nowdays

i dont recomend bounty system honestly most of the time pk is only fun for anybody who can reach the 50's
cuz u'll be able to have a nice epic with a freind but survive the random assaults by the higher levels if u have good stats anyway

Just go to endless...
