Battle Rapture

Pick 1 friendly MORTAL SLAANESH unit
wholly within 18" of the caster that is visible
to them. Do not take battleshock tests for
that unit until your next hero phase. If the
casting roll is 10+, you can pick up to 3
friendly SLAANESH MORTAL units
wholly within 18" of the caster that is visible
to them instead of 1.
