Psychic Duel

Pick an enemy psyker and a friendly psyker.
Each player rolls a D6 and adds the their selected psyker’s Mastery Level to the roll.
The player with the highest total wins the duel,
and drives one psychic power out of the mind
of the loser. The winner may choose a power at random from the powers the enemy psyker
may use and discard it. Ties have no effect on either psyker.
