Abyss room puzzle
The 6th level of the Abyss holds an exceptionally challenging room maze in Ultima IV. It is a complex maze of rooms requiring a variety of procedures to allow the player to proceed.
The Solution[edit]
Note: drinking from the poison fountain on level 5 will allow the player to resist the effects of the sleep barriers.
Start by finding the illusionary wall to the northwest, which leads to room 1 (use the eastern door to enter). Then go south, through rooms 2 and 3, until you reach room 4. Then proceed east to room 5 and then north to room 6, before again heading east to reach room 7.
In room 7, kill the balron in the northeast and stand in the spot where it originated. This will trigger an opening to the south to room 8. In room 8, first kill all foes, before stepping on the spot where the eastern balron originated. Have another companion then enter the illusionary wall east of where the southern balron originated, to trigger a bridge to room 9. Proceed south to reach room 10.
In Room 10, slaughter all the headless with distance weapons, before leaving east to reach room 11. Room 11 houses the final wave of foes, before leaving either to the south or the east, to reach the altar.
