Okay, so mutations can be pretty free-form within reason, and "powersets" should be themed around sci-fi, not fantasy. With that said, what's your general idea of "power scale?" Would something less physically distinguished, like telekinesis, be possible as the result of a mutation, or does it stick to things like retractable claws, extra muscle mass, etc?

Mutations are mostly the latter of what you said. To add there are some cases of mutants being more “unadorned” in appearance. (Basically while there are most certainly the tropey hulkish mutants, sentient “zombies”, and human-animal melds there are those whose physical appearance are less [i]pronounced[/i].)

I had considered telekinesis but wrote it off in the end.

Are the cybernetics and serums on the level that they could allow superhuman abilities?

Yes. 💯 With cybernetics it does depend/vary, but like cybernetic limbs for example can allow for increased strength and leaping ability. (By depend/vary I mean it depends on the applied cybernetics. Design, quality, etcetera.)

And how common are such things to come by in the wastes---are you likely to meet a fellow mutant in any village-sized settlement? Do chromed out mercenaries hang around in all the seedy dive bars? Or do only the rich and powerful have access to these kinds of things?

Out in the wastelands items like functional cybernetics are considered quite a valuable find, to say the least. The best place to find such things are in ruined cities and old military installations or scientific institutions, which of course salvaging for such items is more often than not a challenge of it’s own. In the various settlements and outposts spread across the wasteland people more often than not do not have access to the more advanced tech.

Now, the story is different of course in Ardhelm. Registered/legal cybernetics are a very common sight and are to a certain limitation even being manufactured within the city. Once players have reached the capital there will obviously be easier access when it comes to cybernetics, serums, and other useful gear and items. Basically the further from Ardhelm one goes the more primitive and rustic things stand.

Also, on mutants in settlements, this is rare but not unlikely. Mutants are generally received by the people of Sevara based on appearance. Someone with say a malformed digit or bizarre skin patches would be looked at with curiosity/suspicion but not necessarily shunned as a rule. Now, should someone that resembles the Incredible Hulk come lumbering toward a small trading post they are most likely going to be fired upon. 💀
