The surveyor relic is one of the best relics you can get, change my mind

A high chance of making new resource deposits, many times making new crystal, motes, and gas deposits so that you don't have to waste entire worlds making them (many of the time I get new deposits with 7+ of one resource) for a measly 500 energy credit activation.

Bang for your buck, this is the best relic you can get, and the passive +1 sensor range is invaluable if you don't have/ can't build the sensor array.

Definitely up there, yeah.

The Omnicodex is pretty good too, if you play that style.

My personal favourite, though, is the Baol one. Four free pops that can be put as livestock means I literally don't need to make a single agri district on any of my planets.

Looking over the list, though, here would be the ones I would put at the top - in no particular order

Khan's Throne - 20% weapon damage is huge for the 25x crisis strength fights
Cybrex War Forge - depending on when you get it, 5000 alloys is very nice
Vultaum Reality Perforator - same as Khan's throne, but even better - 40%, though just for a few battles
The Last Baol - see above
Miniature Galaxy - assuming it works for repeatables, quite nice
The Omnicodex - see above
The Galatron - most of the payouts are pretty good, though a few are less useful than others

Why do you want us to change your mind?

It's a joke on Crowders change my mind series.

Rubricator is nice too, since you get infinite artifacts, and is in fact the only way to get them unless you're really lucky with caravans selling them to you.

[Nightmyre]

Yeah, I just don't really bother with relics after getting the secrets unlocked, so that's why it's not on my list

Once researched, you can use minor relics to get a random thing. Research points, a bonus to research for a few years, a start on a technology that can be researches thereafter, or a fallen empire building. Previously the skydome was the only house building buildable on a habitat, but it was really rare to get from doing that.

[Nightmyre]

Yeah I know, but the bonus is usually not significant, compared to the other relics, which are always useful
