Puzzles and hints
Underkeep's puzzles are made of the things around you: a pressure plate, a pit, an altar, a decoration on a wall. Test each one on its own. First work out what the mechanism changes – does it cover a hole, open a gate, move an object or let you into another part of the room?
The hints go from a small nudge to the exact steps. Open them one at a time and stop as soon as you've got an idea to try.
A pressure plate across a pit
When you come back into Hollowgrave Tunnels from the area below them, you reach a pit. There's a pressure plate on the far side, but you can't walk over and stand on it. Before you open a stronger hint, take a look around from where you're standing.
Point me in the right direction
Your party isn't the only thing that can weigh down a plate.
Give me another hint
Find something you can spare and get it to the other side.
Show the full solution
Throw a stone or another inventory item you can spare onto the far pressure plate. A grate slides out across the pit and your party can walk over it.
Three coloured flames
On the way through the cemetery you'll come to a closed gate and three flames of different colours. If you want to work it out yourself, leave the stronger hints closed.
Point me in the right direction
Don't go looking for a key – one of the flames opens the gate.
Give me another hint
Try the blue flame.
Show the full solution
Use the blue flame. The gate opens and the way on leads to Cells of the Forgotten.
Five plates in the dragon's lair
Inside the dragon's lair, five plates with different symbols form a puzzle blocking the way forward. These hints draw on Fahad Suleman's community walkthrough on Into Indie Games.
Point me in the right direction
Check the writing on the wall as well as the plates.
Give me another hint
The text about five stones guarding a sage's wisdom points to an order for the symbols. Step on the plates in sequence.
Show the full solution
Step on the plates in this order: Fire → Crown → Eye → Leaf → Serpent. The door opens, letting you continue.
When nothing seems to happen
Go back to the last state you understood. Check whether the object actually landed on the right tile, and whether a gate opened somewhere you can't see right now. The mechanism may have worked; it just didn't move you anywhere by itself.
In puzzles where you move objects around, having something on a plate may not be enough. It can matter whether the right object is on the right plate, so check the symbol or condition that goes with the puzzle. And if you're not sure which area you're in, compare its name with the Locations and maps page before you use a solution meant for another room.
Change one thing at a time
Make one change and see what it did before you touch anything else. If you move several things in a row, you won't know which one changed the room. Save before you start experimenting so you have something to go back to.
For the statues in Gravewood Crypt, a patch added a reset button.
When the path seems to end
A community guide recommends checking nearby objects you can interact with when you reach a dead end. Open the general hint if searching the area hasn't helped.
Point me in the right direction
Check the furnishings around the dead end too.
Give me another hint
The community guide suggests looking at torches.
Show the full solution
According to the community guide, lighting torches can reveal a path. It gives no location or order for doing this, so treat it as a general clue, not a complete solution to a particular puzzle.
