Rune of Brass

While an enemy PSYKER is within 12" of the bearer:

• Each time a Psychic test is taken for that unit, it suffers Perils of the Warp on any dice roll that includes a double, instead of only a double 1 or double 6.
• Each time that model suffers Perils of the Warp, it suffers D6 mortal wounds instead of D3.
