KitBattle Advanced is a soup-pvp plugin that's very easy to set-up with not too many commands
It's not so "advanced" but it's great for automatic kitpvp gameplay and upgradable kits, etc
Kitbattle features custom Effects, Kits, Arenas, and even Items!
It's a very special plugin and to get this on your server it should cost 100 credits minimum, and a maximum amount of 300
Please add this plugin as it's my favourite all-time plugin. KitBattle Advanced 6.4
