At the start of the Seize Territory step of this Strategy phase, the player with this card can upgrade one of their locations (excluding special locations). Place a Fortified marker on the chosen location. From then on, the player controlling that location rolls a D6 each time an enemy player attempts to seize that location: on a 1-3 that location is seized as normal, but on a 4-6 the location is not seized and remains under your control (the player that attempted to seize that location does not gain any location). This card costs 0 strategy points if the purchasing player controls the Aegis City-shield Generator.
