Melee Caster Class (Mage Class Reworked) is a utility that can be installed on your devices without the need to change the original files. It allows you to turn your Mage into a Melee Caster Class with different abilities and skills. It leans more toward Arcane Warrior players and favors Spirit/Entropy spells if you want to go more Warlock. 

It is very easy to install and use, and the installation process is very simple. The only thing that you need to do is to download the file and install it.
