Ancient Cavern¶
A legendary dungeon with a Rock/Fossil theme, dungeon 28 of 35 in the progression. Entry consumes an Ancient Cavern Dungeon Key and requires Dungeoneering level 55, after clearing Ice Path.
Getting the key¶
Defeating a wild Regirock drops a Ancient Cavern Dungeon Key, as long as your Dungeoneering level is at least 55. Keys go straight to your inventory.
Boss¶
| Pokemon | Level |
|---|---|
 Regirock | 85 |
The boss statue spawns as a Epic tier Pixelmon boss.
The boss gives triple battle experience, guards the boss chest, and has a 2% recruit chance (5% with /frozencrystal).
Mini-bosses¶
19 mini-boss statues, level 80, each drawn from this pool:
Each mini-boss has a 10% recruit chance (30% with /frozencrystal).
Chests¶
13 mini-chests sit at fixed spots through the dungeon, plus one boss chest behind the boss. Each mini-chest is lootable once per run per player (a Moon Key re-opens each one once for a second roll) and holds 1 to 4 items from the Tier 1 pool below. Your first mini-chest of the run also guarantees a Max Potion and a Revive. The boss chest unlocks when the boss falls and rolls a rarity from Common to Supreme that sets its item count and its chance to upgrade rolls into the Tier 2 and Tier 3 pools. See Dungeon Items and Drops for the rarity table.
Experience¶
Completing the dungeon pays 2,200 Dungeoneering XP, multiplied by the number of mini-chests you looted that run (minimum x1). Holding a Dojo Trophy adds 3%, and Double XP events multiply on top.
| XP | |
|---|---|
| Minimum (no mini-chests) | 2,200 |
| Maximum (all 13 mini-chests) | 28,600 |
