Rank 2 Theurge Gift
A mystical sigil burns itself into the ground around the Theurge, visible only to those with Gnosis ratings. This circle drains the Essence from spirits caught within its web. A spider- or antlion-spirit teaches this Gift.
System: The player spends one Gnosis and rolls Intelligence + Occult (difficulty 7). The battle mandala encompasses a radius of (50 x number of successes) feet (or 15 meters per success) around the Garou; spirits (other than the Garou’s pack totem) within the mandala lose one Essence per turn. The mandala dissipates at the end of the scene or when the werewolf steps outside of its bounds, whichever comes first.
