I’d stopped opening them once Brann reached max level. But I was just looting a couple mobs in an overcharged delve and there was a curiosity nearby, so I figured I’d loot it too. Was pleased to see it had more than resonance crystals.
I loot them all the time for Wave Scramblers. They can be rare, but I still have 14 in my Warbank because of it.
I always have more scramblers than I need, so I usually skip the curiosities unless they are directly in my path. But with them containing the currency for the titan console, I’ll definitely be picking them up.
Yes I was happy to see that in the little buckets and pots that I use to just ignore!
I used to get wave scramblers on a semi regular basis because of those. But for some reason they completely stopped dropping for me. Haven’t seen a single one in weeks and I’ve burnt through my stockpile of them.
I didn’t see them for a while either. They seem to have made the droprate very low now.
