A mysterious new branch of study for XCOM, the Psionic Operative utilizes their mental abilities to great effect to boost their allies and cripple the will of enemies.
Class Overview
The Psi Operative in Long War of the Chosen is slightly different from the one in vanilla XCOM 2. Like in Long War 2, some abilities require other abilities to be learned as a prerequisite, but Psi Operatives now also need to gain experience to level up as other soldiers do, limiting the amount of perks that can be trained.
Psi Operatives focus entirely on psionic abilities in their perk tree, leaving little in the matter of using regular guns. However, Psi Operatives get Quick Study, letting them train up Officer abilities faster than other soldiers. The Psi Amp lets the Psi Operative use psionic abilities, improving them and their Psi Offense stat (which is used for Insanity and Domination) as it's upgraded.
Psi Operatives are automatically granted all abilities in the first two ranks when first trained.
In order to obtain certain psi abilities, the Psi Operative first needs to acquire a prerequisite perk (shown with colored arrows on the diagram below):
It's worth noting that abilities which are connected to multiple other abilities unlock all of them at once - for example, picking Fortress adds both Bastion and Null Ward to the pool of available perks for a given Psi Operative.
XCOM Abilities
XCOM row abilities are able to be purchased when the Training Center is built. The cost is 10 AP per tier level.
Training a rookie into a Psi Operative takes 2 days in Rookie difficulty and 4 days in all others. Training a new ability takes a base number of days plus additional days based on the difference between the Psi Operative's rank and the ability's rank:
Base time = 2/4/4/4 days
Rank time = 5/6/7/7 days per rank difference
Times are based on difficulty: Rookie/Veteran/Commander/Legend
Each scientist staffing the Psi Lab will increase training speed by 100%, meaning the training time will be reduced by 50% with one scientist and by 66% with two.
If a Psi Operative is training in the tube and you send them to infiltrate a mission, another soldier can train in that psi tube; the soldier that was in the tube will be on hold upon return from their mission.
