The Catacombs

The Catacombs is SkyBlock's dungeon: a set of floors, each a generated layout of rooms that ends in a boss fight. You start a run by talking to Mort in the Dungeon Hub.¹ A party needs 2 to 5 players; giving Mort a Saul's Recommendation lets you enter alone.¹

How a run works. Clearing the starred mobs in a room completes it and drops an item; some of these are Wither Keys that open the doors along the path. The last key opens the Blood Room, where The Watcher sends waves of undead that must all die before the boss room opens.¹ A run ends when the boss dies, when every player is dead or gone, or after 60 minutes.¹

Rules inside. Outside potion effects are paused and only one potion counts per run (Healing, Mana and Stamina potions excepted). The Auction House, Bazaar and anvils can't be used, and Speed above 100 is cut by a third.¹

Beating a floor unlocks the next; beating Necron on Floor VII unlocks Master Mode, harder versions of all seven floors.¹²

Score and chests. The end score adds Skill (2 points lost per death, 14 per failed puzzle), Exploration (rooms cleared, secrets found), Speed and Bonus (crypts, a Mimic, Paul's EZPZ perk).³ 300 or more is S+, 270 is S, 230 is A.³ Clearing a floor unlocks the Wood, Gold and Diamond chests, an A adds Emerald, an S adds Obsidian, and from Floor V an S+ adds Bedrock.¹ Only one chest can be opened per run, two with a Dungeon Chest Key; a Kismet Feather rerolls a chest once, and unopened chests wait at Croesus for 72 hours.⁴

Dungeon items get stronger inside: each star adds 10% (up to 50%) and each Master Star another 5%, on top of a bonus from your Catacombs level.¹
