With this plugin you can block access to the Enchantment Table and use a command to enchant. When you enchant something it takes that many level from as you entered in the config.yml.
level: protection: 1 [...]
Please note that the amount of levels you enter will be multiplied by the wished enchanting level. That means if you upgrade a wooden sword from SMITE 0 to SMITE 4 it takes the levels multiplied by 4. If you upgrade a gold sword from SMITE 2 to SMITE 5 it takes the levels multiplied by 3.
