Lightning Fast Reactions

Use this Stratagem when an ASURYANI unit
from your army (excluding MONSTER units) is selected as the target of an attack. Until the end
of the phase, each time an attack is made against
that unit, subtract 1 from that attack's hit roll.
The Aeldari can process battlefield events at baffling
speed, making their physical reactions so fast that they
are able to dodge attacks that would hit any other
target.
