Be under the effects of Claustrophobia for 30 consecutive seconds while the Torment “Claustrophobic” is active in Torghast, Tower of the Damned.
Check if Torment Claustrophobic is up
Easiest way to do this is find 5 Mawrats and let them sit on you for 30 seconds.
You can also pull 5 skeletal remains and just let them smack you. There tends to be large groups of them and they don’t hit very hard. Sometimes there are cauldrons that spawn lots of them making this even easier
As a stealth class, you can just stealth near a pack of 5 and wait 30 seconds
Feign death also works
In The Upper Reaches wing there’s a pile of mobs fighting eachother, the “wing npcs” fighting “night fae” npcs, so all I had to do were to stand next to them for 30s while they were occupied and didn’t mind me.
