Custom Blood Magic: Ritual

A Roman emperor named Constantine once during a military dispute with his rival Magentius, also emperor of Rome, was struck by a vision. This vision would be a cross over the heads of your enemies, where it said IN RHOC SIGNO VINCES (At the first sign you will attack). The next morning, Emperor Constantine ordered him to paint a cross on his army's shields, and imbued with conviction he won the battle.

Seeking to replicate Constantine's example, the magicians who created this ritual aim to locate the enemies they have to march on. In this sense, we can use the components that contain the symbolism of that occasion. The wine would be the symbol of faith (not religious), the earth would be the symbol of victory for intelligence (the construction) and the vitae as a magical operator in the connection of the ritual.

By making this preparation and applying it in such a way as to use a glyph under his eyes, the magus' vision will notice a white cross on top of the tarnished target or object.

NOTE: To make the preparation, a container that reflects the magus (silver bowl), wine and vitae of the operator is needed.

System - In addition to the normal Challenge to activate the ritual, the caster must spend 1 willpower and 1 blood point to prepare the material.  The ritual execution time is 5 minutes, instead of the normal casting time for a basic ritual.  Once the Ritual has been performed, for the next Scene or Hour, the caster may ask a Storyteller to secretly throw a Mental Challenge (retest Occult) against any infernalist who comes within the caster's line of sight.  If the caster wins, the they detect the infernalist for what they are.  Note that Investments such as Masque of Innocence will prevent this ritual from detecting the Infernalist.
