Breath of the Swarm

You disgorge a swarm of insects from your mouth in a 5-foot emanation. Other creatures who start their turn within the emanation or move into it on their turn take 1d6 poison damage unless they roll a successful Constitution saving throw. A strong wind such as that of the gust of wind spell scatters the insects, ending the spell early. While this spell lasts, you cannot speak.

Cantrip Upgrade. The damage increases when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
