I got the portal to yugoth the other day. It was a total waste since it doesn’t drop anything good. The only one worthwhile I think is blowback. I’ve gotten it to spawn in sepermeru and the summoning place. The version I prefer is the Cimmerian one since it has a chance to spawn T4 stormsick warriors. All that being said, events are super rare… they hardly ever spawn, so when you see a pointless one like the portal to yugoth, it’s all the more disappointing.
