Shun-Rune

A vicious spell that requires a blood sacrifice. The caster must kill a living being, or find a fresh kill, and allow its blood to spill on the ground. They must dip a finger in the blood and draw the Rune on a flat surface. While its power fades as the blood dries and it becomes ineffective a day after it was drawn, the Rune’s presence will repel members of the species it was created from.

The base difficulty is d8 and the minimum cost is one strain per meter in radius of the space created. Members of the affected species within the radius but separated from the Rune by an opaque barrier feel uneasy and agitated, taking a temporary point of strain each turn. Those within the radius with direct line-of-sight to the Rune take two points of strain each turn. Those looking directly at, or touching, the Rune take three each turn. A break roll always results in the victim fleeing the area. If the Rune blocks a doorway or similarly “controlled” area, attempting to pass it automatically results in a break roll.
