Ok, pure PSI stealth build might be a little op.

Just finished the game.
Oddity XP, hard difficulty. Lvl 25.

Tchort died in one turn. No mutagen tanks destroyed, mutagen puzzle unsolved.

I just literally walked under stealth towards it, then turned on the shield and dropped stealth.

A couple of tentacles moved and attacked, but damage was minimal.

Healed back to full HP to make use of tranquility, moved closer to Tchort.

Thermodynamic Destabilization on a tentacle next to it, Telekinetic Proxy, Implosion on the tentacle, Locus of control, mass Neural Overload, +20 AP adrenalin injection, one more Neural Overload to finish the tentacle — tentacle explodes, Telekinetic Punch to finish Tchort.

No lucky crits involved. Perfectly reproducible. Used one psi booster.

Proceeded to wipe the faceless next for refusing to tell me what the cube was good for.
Yep, PSI build might, in fact, be a bit overpowered. And I was not even using Junkyard Surprised for extra will.

I don't think there's anything wrong with any class in a single player game being op. AND I'm pretty sure on the way up Six teaches you some humility. Screw Six and Faceless acting all high and mighty without ever telling you ♥♥♥♥.

Ironically, you can still get the cube out of DC by simply exporting the character before taking the elevator and importing him into a new game. BOOM: you start the game with the cube in your inventory. But something tells me you will not be able to just hand it to Gorsky, heh.
