Prognosticating Volley

Engaging oracular ballistic contra-auguries, the Deathwatch erect a web of firepower that even Aeldari targets cannot evade through their trickery.
Use this Stratagem in your Shooting phase on a DEATHWATCH unit. Until the end of the
phase, each time a model in that unit makes a
ranged attack against an AELDARI
unit, you can ignore any or all hit roll and
Ballistic Skill modifiers for that attack.
