I mean. She had 2 tailoring daggers. And was visibly dual wielding them. Was kinda cool. Never see 4arms dw.
I feel like we'd seen Shei dual wield before this patch -- and do surprising DPS -- but I don't have logs or screenshots.
Not really a bug when it's working as intended. It's just something that should simply not have been implemented. Anyway, it'll be gone next update.
We did encounter a Shei that was dual wielding prior to this patch. He ended up having a random AKR weapon along with the tailoring shears or whatever. It was really our only time we have ever encountered it, which was a couple months ago. I definitely remember it, because I was barely keeping up solo healing it and spots needed to hit.
