Very very Nice plugin!! The only one in spigot!!
Please, You can add kill custom public message per rank or buying it like a perk? Example: "the player X was scared by X and he death!" Or "the player X was knockedout by X!!". i can buy a new kill message or not, can be works with permissions, that List of kill messages is in the config file, that way each player can choose the kill message that they want!!
