Corruption of the Earth

Corruption of the Earth was a maho spell which caused an area of earth to become muddy, causing any who tread on it to sink down into it. Struggling to get out of the mud would only cause people to sink further. Once the spell ended the earth would return to it's original state, and anyone still in the mud would have to be dug out. A failed attempt to maintain this spell by the shugenja would result in the earth spirits retaliating against the shugenja.
