Add player bounties, so I could add a 1000 coin bounty on my head and the killer would receive the bounty prize.
With a cooldown of 120 seconds probably.
(E.G; /bounty Tominous 1000)
Then it would say it chat
"BOUNTY > Tominous has placed a (bold)1000(bold) coin bounty on (bold)Tominous(bold)' head."
