Arrow of Cursed Fate

Touch a non-magical arrow and imbue it with magic, causing it to put off the horrid stench of rotting flesh. Wherever this arrow lands when shot, every creature in a 5ft radius that is able to smell has disadvantage on attack rolls until the end of the casters next turn. When this spell ends the arrow is instantly rotted away into dirt.

At Higher Levels: At 5th level, the arrow deals an additional 1d4 necrotic damage if it hits a creature. This damage increases by one die again at 11th and 17th level.
