This plugin contains a custom enchantment effect to allow you to retain your exp upon your death. You simply carry an item which was enchanted with RetainEXP enchant in your inventory or armours/tools.
The chance of you retaining your EXP depends on the level of enchantment. Higher lever = higher chance.
Just install TE-RetainEXPEnchant.jar in TokenEnchant/enchants folder. Then you can either "restart the server" or "reload the plugin (not /te reload)". RetainEXPEnchantment will automatically be loaded into TokenEnchant framework.
It would be greatly appreciated for your donation for the provision of support for this plugin.
