The Great Enemy

Use this Stratagem in the Fight phase, when an ASURYANI unit is selected to fight. Until the
end of the phase, each time a model in that unit
makes a melee attack that targets a SLAANESH
unit, you can re-roll the hit roll and the wound
roll.
The Chaos God Slaanesh is reviled by the Aeldari,
who despise its followers with a ferocious loathing.
