Living Plague
The entire area of the spell begins to crawl with worms, flies, and other parasites, continuously devouring all life and each other. Creatures in the area of effect or those that enter the area must succeed at a Fortitude saving throw or take 4d6 hit point damage and 1d4 damage to all ability scores and be affected by parasite infestation for a number of rounds equal to the remaining duration of living plague (a successful save reduces the ability damage to 1 and protects from the infestation but does not reduce the hit point damage). Creatures that remain in the area must save again each round. The entire area of effect is considered difficult terrain, and each creature moving through the area takes 1d8 + half your caster level hit point damage and 1 damage to a random ability score for each 5 feet of movement through the area.
