Psi abilities

Due to a recent genetic mutation, humans in Underrail have varying levels of psionic potential. No one is really sure how this genetic trait came to be, but research indicates that it is a relatively recent genetic mutation. However - it seems to be artificially designed mutation, since so many things about the mutation are just too complex and convenient to be random ones. Hal Roche argued the countrary, believing the mutation would've been way too complex to engineer with existing technology.

Game mechanics-wise, psionic abilities can be seen as the "magic" of Underrail. They're combat abilities that require psi points to use, similar to "spells" and "mana".

Psionic disciplines

Psi powers are split into 3 distinct disciplines - Thought Control, Psychokinesis and Metathermics.

Thought Control

“Ability to influence the minds of other living creatures through mental suggestion and domination. Also the ability to focus and enhance your own mental processes and to take greater control of your body. ”

—In-game description

Thought control discipline is the most indirect of them all and it's also the hardest to get really good at. It is considered by many to be nefarious and mind controllers are often untrusted.

Ezra is the thought control trainer in South Gate Station. He can be found on the SGS level 7 cyber labs. You can also learn Bilocation from the Mysterious Pillars in Silent Isle.

Psychokinesis

“Ability of the mind to exert mechanical force, as well as to emit electric currents and project electromagnetic fields. ”

—In-game description

The psychokinesis discipline is similar to telekinesis with additional electric powers.

Bisson is the psychokinesis trainer in South Gate Station. He can be found on the SGS station platform.

Metathermics

“Ability of mind to initiate and control rapid temperature changes and harness exothermic and endothermic energies. ”

—In-game description

Metathermics is the area of psionic development that deals with instigating rapid temperature changes and chemical reactions. Metathermic abilities consist mostly of attacks that deal heat or cold damage and their side effects.

Quinton is the metathermics trainer in South Gate Station. He can be found on the SGS agronomy level.
