You twist and stunt plants in the area, causing them to wither. In addition to other dangers from failing plant life, this decreases the crop yield for farms. If you cast this ritual in an area affected by
plant growth,
blight attempts to
counteract plant growth instead of producing its usual effect.
Critical Success Completely spoil the crop yield in the area, or decrease the yield by half in an area with up to a 1-mile radius.
Success Decease the crop yield in the area by half.
Failure The ritual has no effect.
Critical Failure The flora in the area changes in an unexpected way, determined by the GM but generally as contradictory to your true desires as possible (for instance, enriching crops when you would prefer to blight them).
