This plugin contains a custom enchantment effect, which launches a firework when you break a block. You can customise the color and type, etc. of the firework in the config.yml.
Just install TE-FreedomEnchant.jar in TokenEnchant/enchants folder. Then you can either "restart the server" or "reload the plugin (not /te reload)". FreedomEnchantment will automatically be loaded into TokenEnchant framework.
