Requirements: The Psyker Talent. Can only be taken during character creation.
From the multitude of Psykers identified within the Imperium each day, you were marked as having the potential to be more than a sacrifice to fuel the Golden Throne. You have been tested, tormented, and subjected to rites and rituals that you shudder to recall — The experience was mentally and physically scarring, but it left you more resistant to the dangers of the Warp and in control of your power.
Your Warp Threshold is equal to double your Willpower Bonus. You also have a symbol to prove your sanctioned status.
