The caster speaks aloud in the Dark Speech whilst drawing infernal symbols in the air, the ritual participants chanting words of power all the while. Throughout the casting time, a dark mist gathers at their feet, sparked periodically by flashes of red lightning and cold blue flames. At the end of the casting, the ritual participants sacrifice one fifth level spell each, whereupon the mist becomes entirely charged with the cold blue flames. Forming Unholy Symbols, the blue-black mist is drawn into the primary caster’s body.

Thereafter, at any point within 33 hours of casting, the primary caster can add +9 when setting the save DC for any three spells that she casts. Each time when doing so, black frost spiderwebs across her hands and feet, melting away at the end of the spell’s casting time.
