MARAUDER’S BLADES (House Clegane Mountain’s Men)
Q: If the enemy is reduced to fewer remaining ranks during the Attack, but before the Panic Test, will the test benefit from Vicious?
A: No. The bonus (+1 to Hit and Vicious) is checked at the start of the Attack
By RAW you should check status at moment of panic test.
Is it so?
