Erupting Infection

With a touch you infect the target with a painful affliction of blisters, boils, and oozing sores. The caster must make a touch spell attack against the target, on a success the target takes 1d4 necrotic damage, and has their movement speed reduced by 5 feet due to the painful and debilitating sores.

At the start of its next turn the target takes another 1d4 necrotic damage. At the end of each of its turns the target can attempt a Constitution save, ending the spell on a success.

This spell’s damage and effect increases when you reach certain levels. At 5th level, the initial damage and start of turn damage increases to 2d4. At 11th level the movement speed reduction increases to 10 feet, and the initial damage and start of turn damage increases to 3d4. At 17th level the initial damage and start of turn damage increases to 4d4.
