Ancient Tunnels
Hidden beneath the Lost City in Act 2, the Ancient Tunnels is a winding network of halls and dead ends populated by undead. Its defining characteristic is the complete absence of natural Cold immune monsters, making it the single best farming zone for Blizzard Sorceresses and other cold-damage builds.
The Ancient Tunnels is an alvl 85 zone where elite packs can drop every Unique and Set item in the game. The lack of Cold immunities means cold-based characters can clear without any resistance-breaking gear. The tight corridors funnel monsters together, making area-of-effect skills highly effective. A Golden Chest spawns at the end of the dungeon.
The entrance is a trap door on the ground in the Lost City, accessible from the Lost City waypoint. Look for the small stone hatch — it can spawn anywhere in the outdoor area but is usually near the center of the map.
- Blizzard Sorceress can farm here with virtually no immunities to worry about.
- The layout is compact enough that Teleport is not required, though it speeds up runs significantly.
- Stack Magic Find heavily — the monsters are not particularly dangerous for geared characters.
- Always check the Golden Chest at the far end of the dungeon.
- Normal monsters here can drop excellent runeword bases including Monarchs, elite polearms, and Archon Plates.
All endgame Uniques and Sets are on the table from elite packs. The zone is commonly farmed for Nightwing's Veil, Death's Fathom, Griffon's Eye, Tal Rasha's Guardianship, and other high-value items.
