Expurgation of Juiblex (3.5e Invocation)

The foulest being in the Abyss, Juiblex, grants you the power to vomit forth the energies of the Abyss against your enemies, coating all before you in a mixture of corrosive slime and burning energy.

If applied, this invocation changes your abyssal blast's ranged blast option to become a Close-range cone. Additionally, instead of making attack rolls, all creatures in the cone are hit, but are allowed a Reflex save for half damage.
