Earthwrack

This spell causes an area of soil to become barren and blighted. Healthy plants wither and die within 1d4 days of casting. No seed planted there will grow for the duration of the spell. Plant-based creatures entering the despoiled area can see the ruin and feel an intense "wrongness" within the soil. Each round they remain within the area, they suffer 1d4 points of damage.

The blight can be cured using a Limited Wish, a Wish, or by casting a remove curse spell (at the 12th level of experience) and a plant growth spell simultaneously.

Most druids consider earthwrack an abomination, although some Shadow Circle druids use it as last-ditch "scorched earth" vengeance against an unruly hamlet.
