Blighted Balm

You coat yourself or an ally with a foul-smelling medicinal poultice that hardens the body against corruption and decay. The creature you touch gains the following benefits for the duration:

Resistance to poison and necrotic damage.

Immunity to disease.

Advantage on saving throws against being poisoned.

At the end of the spell’s duration, the protective mixture dries and flakes away into black dust.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for every two slot levels above 3rd.

Special: You can cast this spell twice per long rest without expending a spell slot if you spend one of your prepared poultices to do so.
