The Topic thread on the Deathbed Curse gave me an idea for a special Mystery Virtue. I don't know if it would be major or minor, but I would like some input.
Mystery Virtue: Sacrificial Empowerment (Major Hermetic Mystery)
This Mystery allows a maga or magus to empower or cast powerful spells, including those with ritual guidelines, by inflicting him or herself with an Ordeal inflicting a permanent flaw. The magus can power up to (Ordeal Modifier) Magnitudes of effect in this way. This also allows the Magus to bend the limits of Hermetic Magic. For example, the magus can use the effect to power an Aegis with Target: Room or Duration: Moon in this way.
Further, the magus need not spend time or vis to cast the effect. It is cast as a Formulaic spell, initiation as normal. The sacrifice can never be reversed, except by highly, highly unlikely Divine Intervention.
The spell can be of any technique/form and may be beyond the scope of the magus's thechnique and form.
To count as a sacrifice for this purpose, a Familiar or Talisman must have been subject of at least 4 seaons lab work. Items which took less than a season dedicated to creating it and it alone cannot be used in this way.
Invocation of this mystery does not itself destroy an object, talisman, etc; the magus must do that independently to activate the power.
Sacrifices may be stacked.
Sacrifices of time, wealth, the completion of quests or travel to specific locations and other such initiation script items do not apply to this Mystery.
Penetration is calculated as normal.
Example:
Confronted by a horde of powerful faerie in the castle of a faerie Lord, a troupe faces near certain annihilation. Help is on the way, but will not be there in time. Johannus, who has the Mystery Virtue Sacrificial Empowerment decides he needs to cast an Aegis to defend the characters until help arrives. He decides on an Aegis of T: Room, D: Moon, and needs to make it a level 50 effect to hold off the most powerful foes (wow, they should not have gone into this castle.)
He immediately snaps his wand talisman in half (+6 sacrifice) and cuts off his left hand (+3 modifyer) and makes some mystery gestures and invocations which ravage his Gift, inflicting him with Deficient Aquam, (+3) for a total of 12 Magnitudes (60 levels) of empowered effect. This easily poweres the level 50 aegis, and Johannus collapses, bleeding and weeping, applying a salve from the Pharmacopean healer as the troupes enemies are helplessly repelled from the door.
The troupe must pray that the invisible bird familair sent with an arcane connection and Aegis token (one of Johannus's fingers) can alert the Covenant in time, so that Arianna can use her powerful Rego magic to teleport them home.
The Covenant owes Johannus some serious compensation!
