I hurt my upper respitory a few years ago, so when the seasons change, I start barking. Normally it draws looks, but for some reason, this year I get a bit more stares…

How about a spell for that?

Wracking Cough

2nd-level necromancy

Casting Time: 1 action
Range: 50 feet
Components: V, S
Duration: concentration, up to one minute

You point at a creature in range and whisper vile words at it. The target must make a Constitution saving throw. If it fails, it becomes infected with a fast acting disease as it begins to cough uncontrollable tearing its lungs apart from the inside dealing 2d6 necrotic damage. Each round at the start of the creatures turn, it must make another Constitution saving throw. If it succeeds the effect end, but if it fails it continues to cough taking 2d6 necrotic damage. Then all creatures that are engaged with the target must also make a Constitution saving throw. Upon a failure, the creature is affected by the spell taking damage as above. If a creature saves against this spell once, it is immune from this one casting of the spell, but can be affected again by a different casting of this spell. Immunity to magical diseases prevents a target from being affected. The cycle of infection continues until all creatures save against the spell or you are no longer concentrating on the spell.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
