Bloodwater

Bloodwater was a common spell used by wizards in Serôs.

Effects
This spell created an expanding zone of blood, within an area of 20 foot (6 meter) radius. This spell could trigger the natural blood frenzy of some sea creatures such as sharks or sahuagin. If triggered, the frenzied creature began attacking any creature near it, whether friend or foe. It could only be cast in water.

Components
In addition to verbal and somatic components, the spell required a material component: a drop of blood.
