We’re still doing tiered mutations, designed for both the GammaFinder and a more comic-book themed theoretical “FreedomFinder” setting (which so far only exists as a thought experiment and a single set of soldier options).

So the next dual-purpose power to get the tiered mutation treatment is ESP.

ESP
You can see a world of pure mental energy, allowing to you send and receive thoughts, and manipulate the pure energy f the mind in various ways. This Extra Sensory Percpetion causes some to call you an “ESPer.” This perception eventually allows you to cast your thoughts into the formless space of the ethereal plane, though doing so is not without risks.
Tier 1: You gain your choice of limited telepathy or telepathic message at will. You gain one of the following 1st-level spells of your choice 1/day (select one): akashic download, detect thoughts, mind link, or share memory.
Tier 2: You can cast mind thrust as a 1st-level spell at will, but it does only 1d4 damage (Will negates). You can now once per day cast any of the tier 1 1st-level spells.
Tier 3: You can cast mind thrust as a 1st-level spell at will, but it does only 1d4 damage (Will save half).
You can now make ESPer checks to see creatures not native to the ethereal plane that are on the ethereal plane, and magic efforts to scry on you. This is a special Sense Motive check, and the DC to spot such things is 15 + 1.5x the level or caster level of the effect that made the target ethereal or allowed it to scry. When you perceive such things, they are within your line of sight and line of effect for your ESPer powers.
Tier 4: You can cast mind thrust as a 1st-level spell at will, but it does only 1d6 damage (Will save half). Each day you can cast one of the following 2nd-level spells once: ego whip, hold person, mind thrust (2nd-level spell), paranoia.
Tier 5: You can cast mind thrust as a 1st-level spell at will, but it does only 1d8 damage (Will save half).
You can now attempt Ethereal Projection once per day. This acts as clairvoyance/clairaudience, but you can move the point of the invisible sensor and your mind travels with it. You can see things that could be spotted with an ESPer check as well as things on your own plane. You can be spotted by any creature with any form of telepathy as if they used an ESPer check. If spotted, they can make mind-affecting attacks against you as if you were at the location of your sensor.
For the duration of the Ethereal Projection, you cannot perceive anything using your normal senses, and cannot take any actions using your body. Your body is considered helpless.
Tier 6: You can cast mind thrust as a 1st-level spell at will, but it does only 1d10 damage (Will save half). Each day you can cast one of the following 3rd-level spells once: charm monster, intellect fortress, mind thrust (3rd-level spell), suggestion.
Tier 7: You can cast mind thrust as a 1st-level spell at will.
Now when you attempt Ethereal Projection, if a creature perceives you and attacks you with a mind-affecting effect, you can use your own mind-affecting effects against it as if you were at the location of your sensor.
Tier 8: You can cast mind thrust as a 2nd-level spell at will. Each day you can cast one of the following 4th-level spells once: confusion, mind probe, mind thrust (4th-level spell), telepathic bond.
Tier 9:You can cast mind thrust as a 3rd-level spell at will.
Now when you attempt Ethereal projection, your body is not helpless. You can perceive through it and take actions, though you must split your actions between using your sensor and having your body act.
Tier 10: You can cast mind thrust as a 4th-level spell at will. Each day you can cast one of the following 5th-level spells once: dominate person, mind thrust (5th-level spell), modify memory, telepathy.

WANT MORE GAMMAFINDER?! OR FREEDOMFINDER?
I now depend on my Patreon for more of my income and support than I ever expected to. If you find any value in my blog posts or videos, I could use help with the Patreon. If you can spare a few bucks a month, it’s a huge help. If not, even just sharing and linking to my blogs, videos, and the Patreon itself is a huge help that just takes a moment of your time.

Thanks, everyone.
