Psycho-reflective Aura is a Tier Five psionic discipline that protects against 60% of all types of incoming damage for a duration of 10 seconds, +20 seconds per PSI.
This is an amazingly good protection, better even than that provided by the Powered Armor.
Psycho-reflective Aura and other psionic shields work well in combination with armor. Psionic shields can also be combined for increased protection. Put up all three psionic shields and wear powered armor, and even the most powerful foe will do little damage to you... until the shields start wearing off.
