Tips for Psi-operatives

  • Stasis — stuns the enemy at one step, making it invulnerable to damage on the move
  • Soul Fire — guaranteed Psi damage to organic enemies, ignoring armor and shelter
  • Unlike other soldiers Psi ability is not exclusive, in theory you can learn all the skills in the tree, if you have enough time and resources. Psi abilities cannot be opened in order. You get a choice of three random from the list, and then to proceed with the training. Training may be interrupted if you want to send operatives on a mission. They will continue training after.
  • Fuse — one of the best abilities in XCOM 2 because of that comedy, in which it activated the explosives on the enemy — dead or alive. Especially if before that you have sent this enemy in a group of opponents with the help of domination.
