Wither

You tap into deathly magic, creating a minor decaying effect around you. You create one of the following magical effects within range:

• You create an instantaneous, harmless, eerie sensory effect, such as a puff of wind, a faint whisper, a sudden chill in the air, the sound of bones creaking, or a small puff of smoke.
• A morsel or collection of fresh food no larger than 5 feet in diameter begins to rot and turn sour.
• Paint or paper peels and flakes off of a firm surface within a 15-foot square. 
• A patch of flowers or other plant growth within a 10-foot radius of you starts to wilt and die.
• A Medium or smaller creature that has died within the last 7 days experiences 1 day's worth of decomposition in 1 minute. Large or higher creatures experience 1 hour's worth of decomposition in 1 minute. This particular effect can only be used once per day on each affected corpse.
• You dim or instantly snuff out a candle, a torch, or a small campfire.

If you cast this spell multiple times, you can have up to three of its 1-minute effects active at a time, and you can dismiss such an effect as an action.
