Savamelekh is one of the first ever demons you stumble into, after all the cultists and possessed mongrels. He was the one that possessed all those underworlders and the one that, inadvertently, made you choose between Wenduag and Lann. This seemingly big demon at the start, but quite weak compared to what we know at this point in the game, has reappeared and is giving some problems to either Lann or Wenduag, depending on your choice of companion. Let’s fix this!
Find Savamelekh’s Mansion | Location – Pathfinder: Wrath of the Righteous
Once you spend some time in Alushinyrra, you will learn from either Lann or Wenduag that Savamelekh is summoning them.
You will have to travel around with a hurting Lann or irritated Wenduag to find the big, bad demon around the Upper City.
If you’ve reached the Southern part of the city, you need to take the other Southern portal to get upstairs and then go down the stairs on the other side.
You can see exactly where you need to get to in the picture above. You need to get to the circled area where an event will start if you have one of the mongrels in your party.
You will then enter Savamelekh’s mansion, if you choose to do it now, and you will find him with some converted mongrels up the stairs.
He will reveal the history of the mongrels to you and then you will end up battling a lot of enemies in order to get to him.
