*The Artifacer of the Infinite has...One issue: Low stats, bar Current (this game's version of Intelligence so we can say the 'mage' is acting stupid without any contradictions). Obviously, the summoning/synthesizing/crafting benefits make up for the stats, and the class still has strong abilities...but taking this class this early will have SERIOUS repercussions later on, due to the exaggerated effect on stats the earlier classes are taken-taking a class with low raw stats will SEVERELY hinder stat growth later. That can be painful, though this won't murder you completely. Of course, the additional ability to craft would be extremely beneficial to the team, and of course, runes and other such things don't make themselves!*

*Are you sure?*
