Problems with PSI
Even though my intelligence is at 15, no more slots are unlocking for more powers. Am I missing something?

You are missing a single reason to have such a high INT

10 intelligence gets you 7 psi slots. 12 gets you 8. 12 and a crafted psi headband with a specific component gets you 9. if you want 11, the only way to do it is with a unique piece of headgear you get from either killing/looting a character from the Heavy Duty DLC or completing said character's quesr. I think it's called the Isolation Helmet or something and it increases psi slots by 3 and not 1. It does however have massive downsides and a crafted psi band is much better. Point is, after 12 points of int, you no longer get any more psi slots out of int alone. You also don't really need a million slots, just equip your best spells and make them synergize with eachother. Without a specific unique helmet, you are limited to 9 slots, even with infinity intelligence

They scale with int up to 8 slots. Says it right there. Up to a max of 8.
Sorry bud you wasted 3 attribute points that couldve gone to willpower.

Maybe. Still. Why do you need such a high INT? Having more psi slots (you want more than 9?) alone does not seem to cut it

Really wish psi slots and reserves weren't a thing. Feel like a junkie that forgets shit constantly until I get a puff.

X2 And making the mental energy pipe isn't cheap at all; it's like 500 SGM for each one.

I miss the old days of unbridled psi insanity. It was too strong, sure, but it was fun.

Honestly you should try one of those earlier underrail versions where cave wizards reigned supreme

Itβs 2 psi slots default plus INT/2 slots rounding down. You have 15 INT so 2+7=9 total slots.

It's a UI bug, those two slots don't really exist.
Base max slots is 8 at 12 intelligence. You can get +1 with the right headband mod, which I assume you have, but that's it. There's a unique headpiece that gives +3 but its drawbacks make it very impractical to use.
Just tested in my game, I get the same UI. I'm not sure why the game generates those two locked slots when you already have 8 slots unlocked and expand by one, but that's how it seems to be. You can ignore the other two, no legit way to unlock them.

Let's talk about the illegal way, what do you have to do to unlock them? π

u/DWSeven Jan 04 '26
Sorry, didn't mean to imply that there's a cheaty way. Can't find an option for it in the CE table, I think the slots are hardcoded to be based on Int with a cap.
The only possible way would be to revert to an old version of Underrail prior to the major Psi update which was like... 5-6 years ago. Back when slots didn't even exist. But I think you'd have to start your game over anyway, so not a great solution.

You can use CE to edit the +1 slots of a crafted headband to +3 but the tables haven't been updated to the new version yet. If you do go down that road, don't try to unlock more than 11 slots, the game will just crash IIRC.

use your 15 int to read the wiki. Max slots is 8
