I’ve just captuerd Vattende, Confessor of Asura 
You’re luckier than me. I did Sinner’s Refuge yesterday, the 1st time since I started playing CE 3 months ago, but only found a guy named Sir Bowen who dropped just the boots. I didn’t try to capture any thralls I was there for the brimstone only.
Congrats and enjoy ! 
I am so sorry for that.
