Still feeling like crap and having my friends avoid me means I only get to talk to myself and the magic elves I see from the cough syrup. Here is another spell where you can make your friends sick!
Plague Wind
2nd-level necromancy
Casting Time: 1 action
Range: 30 feet cone
Components: V, S
Duration: Instantaneous
You cough out a vile purple mist that envelops all targets in range. Any living target that breaths must attempt a Constitution saving throw. If it fails, it’s lungs, mouth, and sinuses instantly fill with sickly brown mucus. Each round, any affected targets must attempt a Constitution saving throw to breath and act normally. If it fails, it falls prone losing all actions for that turn. After succeeding at or failing two saving throws it successfully shacks coughs out the mucus returning to normal.
