Above, you can find the map of the Flooded Caves. It is an underground location connected with Crestwood and the Still Waters side quest. In the cave, there is a rift that is being heavily guarded by monsters, but this is not the only attraction awaiting you here. You can also find many valuable treasures in this place - some of them are in the spots that you need to cut your way into (as the fighter) or burgle into (as the rogue).
Note - While leaving the Flooded caves, remember to take the alternative way out (the ladder), thanks to which you reach a cave in Crestwood that cannot be accessed in any other way.
