Opacus Fragor

Opacus Fragor is an advanced offensive spell, exclusive to Daemons and those in possession of the Tome of Nosferatu. Although it can be used by most Daemons, it was typically only taught as a war skill to generals. The creator of the spell is unknown, but it is typically attributed to an unnamed Daemon mage. There are currently no official laws against this spell, but archaic spells of this magnitude and type are typically considered forbidden.

The only non-Immortal currently able to use this spell is Risel Faust.

Description and Effects
Casting this spell will summon an explosive force upwards from the placed magic circle, erupting in a black fire that causes magical burns. Both the explosive impact and the fire will cause damage to anything caught in the spell's large area of effect. This spell is usually cast from the ground, but it can be cast in any direction, such as downwards from the air, sideways, or on a diagonal, for different projectile angles. The visual aspect of this spell is a black-purple cloud of explosion, followed by a black flame which emits a faint purple light. After the initial casting, small spots of black flames may remain for extended periods of time. The flames created by this spell cannot be put out by non-magical water or other non-magical means.

Cast time for this spell is on the quicker side for an advanced rank spell, at just 30 seconds. The flow of mana does not need to be maintained after a successful cast of this spell, as the explosion is not a prolonged-effect type of manifestation. This spell can be chain-casted, however it can only be chain-casted with itself. Changing the area of effect during a chain cast with this spell is only possible to a small degree -- about 2 to 3 feet in any direction. The only aspect that can not be altered at all during chain casting is the angle and direction of the explosion.
