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.

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, which draws its spawns from a different pool of bosses.

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.

During The Final Assault, 6 of the following 10 bosses will spawn:


 * in Sorrow's Belly Tanzit Razorstone and either Grognard Gravelhead or Malinon Threshammer


 * in Iron Arch either Gardock Stonesoul or Ivor Helmhewer, plus either Korvald Willcrusher or Garbok Handsmasher


 * in The Forge Heart Rago Kindlerock and either Runar Brimstone or Galigord Stonestrike

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

There are 10 spawn points:
 * Sorrow's Belly, one near the North Eastern (left) gate, one near the South Eastern (middle) gate.
 * Iron Arch, one near the gate to the forest, one near the gate to the Forge.
 * the Gap, one by the crushers, one near Marshall Whitman, one near the gate to the Forge.
 * The Forest, one right on the Stone Basilica, one patrolling on the forest ground right in front of the Basilica, one near the gate to the Forge.

The bosses who spawn at these points are randomly chosen from a pool. So far the bosses who have been confirmed in the pool are:
 * Brohn Stonehart
 * Tarnok Forgerunner
