Hi this plugin aims to be similar to SaicoPvP their HeadHunting system.
So basically what the plugin does is the following:
It makes mobs that are in a headhunting level drop heads that can be sold by a player for money.
It makes players grind their way to be able to place more spawnertypes.
/GiveHeadHuntingXP %player% %amount%
/GiveSpawner %player> %spawnertype% %amount%
/Level %level% (Shows information regarding the level of headhunting)
/OpenSellHeadInventory (Command to open a sellhead inventory useful for NPCs also used if enabled in config)
