Amulet of the Voidwyrm

• The bearer has a 4+ invulnerable save.
• Once per battle, when an attack is allocated to the bearer, it can channel the Shadow in the Warp. If it does so, the saving throw is automatically a 6 (do not roll).
• Each time the bearer declares a charge, enemy units that were targeted by the charge cannot fire Overwatch or Set to Defend against that charge.
