This plugin contains the custom effect that allows you to harm other players using ArmorStand + VoodooEnchanted Player Head !!
Once you enchant player's head with Voodoo enchant, place it on an armor stand. Then simply hitting (left click) the armour stand will give the voodoo-ed player damage!
Currently, it only supports entity attack event, but I'm planning to support giving damage with other means (such as potions).
Just install TE-VoodooEnchant.jar in TokenEnchant/enchants folder. Then you can either "restart the server" or "reload the plugin (not /te reload)". VoodooEnchantment will automatically be loaded into TokenEnchant framework.
