Epic RPG: Class Artifacts

This version is geared towards a complete rebalancing of the mod and the addition of the final systems to finalize the gameplay.

• The damage artifact, which wasn't increasing damage as expected, has been fixed; its attribute has been changed to melee damage.
• The effect level of the sets in their first version has been changed so that everyone uses the same level (this will change in later versions as the new system will add incredible and fun improvements).
