Blood leech

Blood leech was an invocation realm spell, a powerful ritual that could be cast only by drawing mystical energy from the land. It was designed to steal a fraction of the power inherent in a person's bloodline, and took a whole month to put in effect.

Effects
With this spell, a small portion of the power that some Zakharans inherited from the seven followers of the Loregiver could be transferred to the caster. The victim had to be within 20 miles (32 km) and known to the caster. Blood leech could affect a person only once during their life.

Components
This ritual required power from a land with a strong natural flow of magic. The caster also needed to invest materials worth 2000 gp, a pinch of bloodsilver, and some of their metaphysical power of rulership.

History
Blood leech was one of the means used by the infamous yak folk of northern Zakhara to gain access to the bloodlines of the Sharit and the power they granted over the land.
