This is an Idea I made for something more different but I think it can fit well into current Curse Craft.

A contract system much like the Star Plasma arc where players will get a contract to either protect or kill randomly selected player. Contracts cannot be made on players with a grade below Grade 2.
After a period of time if that player is not dead or is dead, the players who completed the contract will gain the contract rewards. If the contracted player DCs during this period of time the contracts will become void and a vote will begin. If the vote is passed by a majority of the players in the server the contract will be reinstated on another random player. If this happens a 2nd time no vote will be given to the players and the Star Plasma contract will be put on a cooldown. Contracts can only be given if the server has a minimum player count. If count is high enough multiple contract targets can be made.
Players can only be apart of the Star Plasma contract system if they are in a certain realm (Heian, Shinjuku, Badlands, etc.)
