Venomous Influx

You instill poisonous miasma into a nearby
creature. The creature makes a Con save. On a
failure, it takes 4d8 poison damage and is poisoned
for 1 minute. On a success, takes half as much
and isn't poisoned. At the end of each of it's
turns, it can make another Con save. On a
success, it is no longer poisoned.
At Higher Levels. When you cast this spell using
a spell slot of 3rd level or higher, the damage
increases by 1d8 for each slot level above 2nd.
