cast bloodmist <target>
This spell uses some of the casters blood to create winged demons that claw and bite the target. The demons are very short lived but can often get in several attacks before being destroyed.
Note that bloodmist demons generally avoid killing the target outright. When the target is mortally wounded, the demons will stop, allowing the necromancer to soulsteal if desired.
The spell is named 'bloodmist' because the demons, when destroyed, explode into a fine mist of blood which tends to hang in the air like a red haze.
Instead of using blood directly from the caster, it's possible to use previously bottled blood. Blood from the caster works best and can reduce the spellcasting mana cost to a very small amount. Blood harvested from corpses still requires the full spellcasting mana cost.
Using one's own blood for the spell while affected by the 'foulblood' spell will cause the bloodmist demons to inflict poisoned attacks.
