Diablo III boss guide

The Lord of Terror is back and once again attempting to rule the world. Third time’s a charm, right? In this installment he has plenty of help spread across the globe trying to stop you. If you’re looking for an edge against the hordes of powerful demons you will face, then look no further. Inside you will find every major boss fight found throughout the game.

Each section of our guide will provide you with information on how to best combat every boss. We’ve presented all their moves, attack patterns and weaknesses that you’ll need to know to take down each boss.

Disclaimer: This guide represents bosses on Normal difficulty and if you"re fighting them on higher levels you should expect damage to scale up along with their health and resistances.

    All bosses in the game are an annoyance at best. Real game is in elites. Let me know when you tackle a -Jailer Vortex Desecrated Arcane Invulnerable Minion- spawn in a tiny hallway

    Haven't seen a 5-skill champion/boss yet. Is that later in Inferno? As for me: (Waller, Frost, Arcane, Mortar) in Inferno Act 1 killed me rather quickly, repeatedly, and with no mercy. It was rough and almost made me quit the game and reload since it was the tight corridor right after you break the Templar free in the main quest. Another one that really sucked was a (Frost, Horde, Invulnerable Minions) tongue-lasher boss in Hell Difficulty, also in a small room right next to the entrance of a quest dungeon.

    I only had problems with the last 2 bosses on normal, even then it was max 3 - 4 attempts before a kill (lvl 30 witch doctor).

    Lightning Inferno. Not Flamethrower. Get it right.

    I prefer "Lightning Hose"

    Good guide that outlines all boss's attacks. However, don't be deceived. This guide makes it seem like some bosses are a walk in the park, when in reality they will give you quite a hard time. As a Demon Hunter, Belial, Rakanoth, and Diablo all gave me particularly hard times.
