An interesting mechanic is that Fire Magic has a “Fire Wall” pet that just stands around and burns things. It’s implemented as a pet internally, but since it’s a wall, it can’t follow you around. It’s more like a trap.<ref>http://www.eldergame.com/2012/07/a-little-more-about-evil-undead-and-pet-classes/</ref>(it can also be killed by enemies)
