Apologies if this has been mentioned earlier, I tried to search but I am hopeless with the functions due to my bad English.
The Basic Training mission after the Prologue informs you that using your ability (Psykinetic’s Wrath) will lower Peril, which it doesn’t do due to the Talent Tree changes made to the abilities. This has caused some confusion with new players (like myself) as to why the game is lying to you.
Hopefully this tutorial can be corrected at some point to avoid further confusion
