Also I am having issues moving around feats on mobile. Currently at the doctor's >
I took the liberty of redoing your feats as well, so this now isn't really "your build but optimized" as it is "a build I recommend for you." As such, you should feel free to ignore this suggestion because it's not really considering what you like to do as you play. That said:
You need Premeditation. Any psi build without it is flat-out wrong. Premeditation and Locus of Control are the two ultimate "I win" feat abilities for psi, and you should always make room for both of them. I also stripped the feats I don't really think add much to psi. I didn't explain before, but I'll offer an explanation below the link in case you care.
http://underrail.info.tm/build/?GQMDAwYFEAoAAAAAAABCUWgAAEtfFk9QX8KHwocxAEArUCgsFCplLj0hBWdmTelekinetic Undulation: might be worthwhile for Tranquility, because then TK Proxy is only 5AP, but for Psychosis you don't have the luxury of hitting as many abilities per turn so you really will only proxy to double up your TK Punches and Implosions. Also, daze isn't really terribly helpful.
Hypothermia/Cryogenic Induction: Even though Hypothermia can reduce target Fortitude (which in part scales with CON) your Psychokinesis score is so high that you'll almost never get your TK Punch stun resisted, and that's all you have to worry about (Electrokinesis stun can't be resisted unless the target takes 0 electricity damage). CI, which potentially helpful, isn't going to see a whole lot of use for you because as Psychosis, your alpha strikes are going to be devastating. No point debuffing a room full of corpses.
Doctor is strictly worse than Fast Metabolism, though the two do stack so there's no reason you couldn't take both if you felt like it. Fast Metabolism also affects your Regen Vest heal, which is a really big deal on higher difficulty levels; doctor does not. And as long as you loot them when you find them, you're going to have *so many* health hypos that you can stim up into bandaging range if you're badly hurt.
Mental Subversion: not useless, but most of the time you're going to be killing things so quickly that you don't have time to stack the debuff. Also, with 16 Will and a Uni-Psi headband and a Psi Beetle Carapace tac vest, your effective Thought Control skill will be so high you clear resolve checks anyway.
Nimble: Sounds good, but only amounts to about 5 MP per turn - that's half a tile. Mostly you'll be using stealth to get ideal positioning so you won't need to run far. And when the expansion hits, you'll find Nimble even less attractive than it is now, trust me. (or don't! I'm not the boss of you).
+Paranoia: the stealth detection will be nice considering you have a fairly low Perception. It sucks getting mauled by Crawlers and Lurkers just because you didn't see them in time.
+Premeditation: I'm serious, you need this. Need it.
