Corruption

Your Patron uses you as their conduit to touch the World, but their touch brings only ruin.

You allow your Patron to influence the World through you corrupting an area of 15 ft around the spells center. Any creature within the area of effect must make a Constitution Saving throw or suffer 4d8 points of Necrotic damage, a saved throw takes half damage.

At Higher Levels: Add 1d8 points of Necrotic damage after level 5
