When Revealed: Each player makes a Fortitude test. If you fail this test, deal 1 damage to each character you control. Until the end of the round, treat the printed text box of each damaged character as if it were blank (except for Traits).

Shadow: If you failed a Fortitude test this round, this attack is considered undefended.
