The Watergod's Altar | Act II Dragon's Dogma Guide
Last update: 11 May 2016
In short: A journey to a mysterious cave.
Difficulty level: Medium. You'll be fighting Saurians and a Cyclops.
Begin the quest by talking to father Geoffrey at the Cathedral near Ser Maximilian (in Gran Soren's noble quarter). Then, head for the titular location west of The Mountain Waycastle.
Once you're at the castle ruins, go down towards the river.
At the riverbed, turn left towards the spring. Climb up the hill until you see a way down (in front of the waterfall). This is where you need to cross the stream.
Under the last waterfall there is a monk, Haslett. Talk to him and enter the cave.
Go straight ahead until you reach a drawbridge. The mechanism that controls it is missing a lever. Go down the nearby stairs.
In the caves below you'll encounter a large group of Saurians. When you kill enough of them, the rest of them will retreat, opening a way. At its end you'll find three chests - one of them holds the lever you're looking for.
The next step is of course going back up, attaching the lever and lowering the bridge.
You'll find yourself in a large chamber with a fragmented floor - watch out for the water below because any contact with it means death. First, go right to kill off the enemies and take the loot.
Then, go back to where you started and use the left path. A couple of Saurians will try to surprise you by jumping on the plank.
This way leads to a chamber with columns and a Cyclops. Examine the corpse of a man - that's what you're here for. Report back to Haslett in front of the cave. The monk will ask you to finish the case.
Go through the caves again to reach the chamber with columns. This time, kill the Cyclops. Take his eye.
Retreat in front of the bridge and take the dark corridor which ends with a closed door. Use the eye here.
Kill the enemies behind the door and go gown the stairs to the room below, which is controlled by the undead.
Afterwards, take the only available path. At its end, activate the switch on the floor. The water level will drop.
To finish the quest you also need to find five altar slates. They all weigh a lot, so distribute them among party members. Search the open paths - there are passages that have been previously unavailable because of the water level.
Three slates are on the lower level - the last of them has been hidden in a chest at the end of the cave. The winding road is guarded by a small Cyclops.
Two other artifacts are on the upper level - don't use the stairs, but the ladder below (in the side rooms).
Having collected all the slates, go back to the monk to finish the quest.
