Sorrow's Furnace Boss Locations

The following is a listing of the different boss spawn locations in Sorrow's Furnace. While entering the Furnace without quest will usually provide a random spawn (among fixed spawn points), entering the Furnace with one of the quests from Grenth's Footprint will cause a pre-determined spawn of bosses, as follows:

Bosses during Galen Trask's Quests
This spawn requires players enter the Furnace with Galen Trask. Bosses (and Stone Summit in general) cannot be attacked in this spawn due to the Chains of Enslavement spell.

Bosses during Kilroy Stonekin's Quests
This spawn requires players enter the Furnace with Kilroy Stonekin.

Bosses during Orozar Highstone's Quests
This spawn requires players enter the Furnace with Orozar Highstone.

During Orozar's quests, the following 6 bosses will always spawn:
 * Tanzit Razorstone
 * Drago Stoneherder
 * Brohn Stonehart
 * Villnar Painforge
 * Vokur Grimshackles
 * Galigord Stonestrike

These 6 bosses will always appear in the following 6 places, though who appears where is random:
 * The Gap where Marshall Whitman would be if you entered the Furnace without any NPCs.
 * The Gap entrance to the Forge Heart.
 * The Stone Basilica.
 * The Forest entrance to the Forge Heart.
 * The Iron Arch
 * In the passage from the middle door of Sorrow's Belly to Iron Arch

These 6 bosses will never spawn among the waves of assaults during Noble Intentions, nor be part of the pursuit during Noble Intentions Plan B.

Bosses during High Priest Alkar's Quests
This spawn requires players enter the Furnace with High Priest Alkar.

Bosses during The Final Assault Quest
This spawn requires players enter the Furnace with Ennis Granitestrider and Budger Blackpowder.

Bosses if entering with no Quests
This spawn requires players enter the Furnace without any of the NPCs from Grenth's Footprint.
