Compost

The ability to quicken the transformation of waste into viable healthy compost. A compost pile roughly the size of a 5' cube will be turned into viable, and incredibly effective, compost fertilizer 24 hours after casting. The pile will become exceedingly hot, steamy  and odoriferous during this process. 4 hours after the casting the area within 30' of the pile will be subject to the effect of the stinking cloud spell. Anyone coming in direct contact with the pile will suffer 1d4 fire damage per round. These effect persist for 16 hours. The pile then enters a  4 hour cool-down period. It is still unpleasantly warm and pungent but will no longer cause damage. At the conclusion of the spell the volume of the pile will be reduce by half but the remaining material will be an incredibly nutrient rich fertilizer that will increase the health an productivity of any cultivated flora.
