Bloodstars

Bloodstars was a rare evocation spell used by wizards.

Effects
Bloodstars created seven spiky electrical stars from the caster's blood that whirled around the caster. The caster could direct the bloodstars to attack up to seven different targets, though only one bloodstar could strike a particular target at any given time. Bloodstars could not move more than from the caster. Bloodstars moved with dashing speed and accuracy, ignoring armor and other non-magical barriers.

When striking a target, a bloodstar lodged itself in the target to cause harm. Once the bloodstar was attached, the caster could detonate it when they wished to cause additional harm to the target and any other creature standing within. Bloodstars, even upon exploding, never harmed the caster.

Components
In addition to verbal and somatic components, this spell required drops of the caster's blood to cast.
