Runes, keys and crafting supplies
Chaos Sanctuary elite packs and Diablo
Chaos Sanctuary combines dense elite packs, seal encounters, and Diablo in one repeatable route for runes, gear, and experience.
WHERE & HOW TO FARM
Chaos Sanctuary elite packs and Diablo
Chaos Sanctuary in Act IV, reached from the River of Flame waypoint.
Before you go
- Reach Act IV Hell for the endgame route.
- Have sufficient resistances and damage for elite packs and Diablo.
- Bring an alternate damage approach or a way to bypass immunities your build cannot handle.
Farming steps
- Take the River of Flame waypoint and enter Chaos Sanctuary.
- Clear reachable elite packs while locating the three seal areas.
- Activate the seals and defeat the seal bosses that appear.
- Pick up useful runes, bases, charms, and gear as you clear.
- Defeat Diablo after completing the seal sequence.
- Return to town to store the haul, then reset and run again.
- If the area is currently Terrorized, consider it for experience and broader high-level item potential, provided your build can clear it.
- Avoid losing time to an immune pack your build cannot damage; move on or use your alternate damage source.
Repeat, collect and use
Repeat as often as useful; drops are random and the route offers no guaranteed specific rune or unique.
Common mistakes
- Skipping the seal sequence and leaving before Diablo appears; activate all required seals and handle their bosses.
- Fighting every resistant pack despite poor damage; bypass or use alternate damage to maintain pace.
- Treating Magic Find as a rune multiplier; it changes item quality rolls, not rune drop frequency.
When to stop or switch
Switch to another farm if the Sanctuary’s immunities, deaths, or layout consistently cut your clear pace.
