Ars Magica 2 Bosses is one of Ridgedog's series on the Yogscast Complete server. His goal for this short series was to make videos on all of the bosses in the Ars Magica 2 mod. During these videos, he fights the bosses and explains optimal skills, locations and gear to take the bosses down. He includes helpful tips and instructions, as well as random trivial facts.
Ridgedog only covered two bosses in 2014 - the Water and Earth Guardian, and did not progress further.
