Divinity: Original Sin 2 – Cat Person Achievement Guide
Desc: Rescue Arhu
How: Paladin Kem is holding Arhu hostage in his super-secret underground lair. You can find the entrance hidden in Kem’s in his garden. There will be a lever that you need some Wits to see near the water pump. Once pulled go on down and there will be some guardians there. Kill them and when they are down drain them of their Source. At the end of the hall, there will be 2 pictures with a gap in the middle. You will need the third picture from a little orphan girl in the sewers. Once you have the picture place it right in the center and you will unlock the door behind the pictures.
Before you go in find a picture named “(I don’t recall the name, it has to do with strength)” hidden among the junk down here. Go down the pathway and find the God King altar. Place the picture on the pressure plate and a pathway will open. Head on down and you will find a dungeon that Kem has made. Arhu is being held captive. Free him from those chains by using your spooky vision and getting rid of the people holding the chains. Arhu will complain but he will be fine. Paladin Kem will show up and there will be a fight. Keep Arhu safe and kick Kem’s booty. Once you have won the fight and escorted Arhu out, you will get the achievement.
