Deadly Carrier

3rd-level necromancy

Casting Time:1 action

Range:Self (20-foot-radius sphere)

Components:V, S

Duration:1 day

Choose one disease you are infected with. You become immune to that disease but continue to carry it, and you become very contagious to others. If the disease does not already have game mechanics for its contagiousness, assume that anyone spending at least ten minutes within 20 feet of you must make a Constitution save against the disease or become afflicted with it.

Any creature you infect has the normal disease infection rate (not the enhanced rate of the spell).

This spell has no effect if you are not currently infected with a contagious disease.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the duration increases by 1 day for each slot level above 3rd.
