If you drop down to the lower levels when you spawn into the riad you'll find a maintenance area with 6 levers and me and my friend confettiNSorrow found the pattern to pull them with lableing the levers from left to right 1-6 the code is 1 5 3 2 4 6 and this triggers a noise and text "a path is now open" appears and a new miantence area opens up all the way on the far left side on the first level beneath the river in wich there are six new levers that seem like they need to be pulled all at the same time since they dont stay down when pulled and this where got we got stuck since theres just two of us if anyone else can get further please leave a comment and help us figure this secrect out. Update:Confetti found a new tunell open in the center right undar the paace entrance that leads to some parkour over some water to a fan that can be actived to blow you deeper into a maintenance shaft going up the shaft leads to a door that hold some watchers that alert security troop it seems that you can use this to skip past the entrance encounter to the riad and enter the baths encounter. Update: these shafts are a maze its going to take forever o explore it all please send help! Update: it seems these shafts are to bybass encounters and rewards you with extra chests for loot for encounters you do do but you cannot emter into the final boss room. Theories 1. This is stuff for the hard riad and challge modes 2. A way to back track or skip and find extra loot 3. You need to enter this area for the riad exotic and find items in here behind some gold embroidered doors that we couldnt open or with some more levers we found but couldnt interact with.
