Deceit (Ultima V)

True to its name, Deceit in Ultima V has devious mazes, puzzles, and traps. However, the Underworld can be reached very quickly, albeit, at the cost of some health:

Level 1: Jump in the "Bottomless Pit"

Levels 2–7: Fall uncontrollably

Level 8: Land in a room full of sea serpents. Quickly exit to the south (or kill them and shoot the gems to collect them). Go all the way south and then into the next room. Using the Crown will expedite the adventurer though a gauntlet of daemons and dragons in this room and the room to the west; both have triggers that release groups of minor enemies as well. Leave through the southern exit and in the next room (room 15), release the triggers in the order shown on the map below.

The Underworld below Deceit holds the Shard of Falsehood. The return trip will be much longer, since the room with the sea serpents will not be reachable from the Underworld.

Level 8: Pass straight north through the dragon rooms and take either ladder.

Level 7: Go south and into the room, then east and up the ladder.

Level 6: Search to reveal the pit trap at the intersection, then head east or west and up either ladder.

Level 5: Head north and take the ladder up.

Level 4: Continue up.

Level 3: Dispel four fields and fight/avoid four daemons and continue up.

Level 2: Head north, drink at the healing fountain, and continue up.

Level 1: Find the hidden door at the southern end of the corridor and go through to reach the ladder to the surface.
