Psychogenic Endurance

Psychogenic Endurance is a Tier Four psionic discipline that increases the player's Endurance by 2.
The power does not stack and the maximum END value is 8.

Duration: 2 minutes + 1 minute per PSI

Analysis[]

Extra Hit Points are always helpful, especially when going against particularly tough opponents. These extra HPs are lost when the power runs out, but your health will be never reduced below 1 Hit Point.
On higher difficulty levels, each point of Endurance gives you fewer Hit Points. However, since you have a lot less Hit Points to begin with and the upgrades are more expensive, the additional HPs - even if fewer in number - may be proportionally more valuable to you.
Endurance also has influence on Radiation and Toxin damage, partially reducing their effects on soldier's health. This is especially useful on highest END, since at the maximum value hazards cause (next to) no harm.
