Crippling Vertigo

Crippling Vertigo has a casting value of 6.
If successfully cast, pick 1 enemy unit
wholly within 18" of the caster and visible
to them. Until your next hero phase,
roll 2D6 before that unit makes a normal
move, a charge move or a pile-in move.
If the roll is greater than that unit's
Bravery characteristic, it cannot make
that move.
