Nubilus

Nubilus is a minor offensive spell, exclusive to Daemons and those in possession of a Forbidden Tome. The creator of this spell is unknown, but it is believed to be a spell that is innately known by all Daemons, which would make its creator the Seven Goddesses. There are currently no laws against this spell.

The only non-Eidolons currently able to use this spell are Risel Faust and Eidol Weissgreen.

Description and Effects
Casting Nubilus will summon a wrath of umbral energy below the target. This energy originates from the magic circle, thus it is possible to cast this spell in the air so as to hit an airborne target. The umbral energy damages the target in a manner similar to burns, although it will not cause physical burn marks. Occasionally, areas of the body hit by this spell will bruise, forming purple bruises. The visual aspect of this spell appears as a dense purple mist that takes a form similar to flames which surround the target, and dissipate as the spell ends.

Cast time for this spell is almost instantaneous, at about 0.01 seconds, and takes only a minuscule amount of mana. Due to this, it is a remarkably easy spell to chain-cast, although switching targets in the middle will be difficult. The typical effect duration of this spell is 30 seconds, but it can be extended up to 5 minutes if the caster continues to put mana into it rather than ending the flow after casting.
