Defeating the Uber Bosses or "Ubers'' is all about acquiring a Hellfire Torch. The Uber Tier List ranks completed builds in accordance with their competence and consistency for killing them. This includes speed of defeating the mini-Ubers and Uber Tristram. A build's ease of surviving the Ubers and the minions that surround them, is also taken into account. Every Character Class is represented by at least one build.
