I got a review copy from the Dev to test it and review it.
The language config needs more options like for Mana and Hot Bar etc. The default colors could be cooler. Add a command to disable the scoreboard. The config is super easy to understand and configure. Definitely need to add the decimal to the default Mana per sec. The equip GUI is AWESOME! Maybe add clickable messages to spells list(but it has the GUI)? The slot has to be empty to use the spells which kind of sucks, maybe add a config option? Putting a item in the spell slot cancels the spell. You can't hit the mobs with your hand or item to use the spells, config option? Add a item wand to assign the spells to? I gotta say for the price and what its offers, this is pretty cool plugin.
