Maybe stick to hideaways? Those can escalate to a 1/10 i believe. And yes anoms always escalate to the same expedition.
Oh boy… these are weird. I’ve been playing 8 years and I’m not 100% sure what’s going on with most of them. So full disclosure, I might be wrong about some of this stuff.
The ones under “DED Deadspace Report” are stationary rated sites. Most are 1/10s in starting areas and were part of a new player experience revamp back in 2015, though they don’t seem to really get used for much anymore. There’s no indication to a new player that they even exist and the new player experience has since been revamped… again. They seem to have been intended for new players to do small sites without having to scan but anomalies accomplish that end as well and they’re more common.
Others are older than 2015. I remember some going back to when I started playing Drakes online in 2010. They might be of value. I’ve heard of some in lowsec or out in NPC null that are quite valuable but information on them is sparse and they apparently get farmed repeatedly by locals, with strict rules on how they’re supposed to do them. I’m not 100% sure though, just rumors.
The ones under “DED Agent Site Report” are also weird. Some are sites designed for COSMOS missions which drop a hand in item that can be bought and sold from a contract. COSMOS missions are really old and in a dev ama a while back I remember a dev saying they were leaning towards removing them from the game because of all the problems they have. They give a massive amount of faction standing though, so they’re worth doing. Many of these sites are farmed repeatedly for items such as “Isone Flosins’s Corpse” or “Maqeri Cancen’s DNA” to be sold on contracts.
Also under DED agent Site Reports you’ll find various odities such as the ubiquitous Abandoned Battlefield, Abandoned Gallente Outpost, Natural Phenomenon, Roden Shipyards Manufacturing and many others. As far as I can tell they seem to only exist for the sake of lore. You fly there and get some flavor text and that’s about it.
So to make a long story short. Just ignore them. The only value they have are for cosmos missions or if you have access to one of the ones out in null/lowsec.
