Rank 1 Theurge Gift
The Theurge casts out an invisible, mystic net which entangles hostile spirits, confounding them with a mixture of magical force and long-broken but still potent Gaian law. An owl-spirit teaches this Gift.
System: The player spends one Gnosis point and rolls Intelligence + Occult (difficulty 8) as an attack directed at a spirit within 30 feet, which can be defended against normally. Rather than inflicting damage, this attack reduces the spirit’s effective Willpower by two for the purpose of all combat actions for the rest of the scene. Multiple applications of this Gift don’t stack.
