Activate (manipulate)

Derived from a mixture of krooth venom and an agitating agent, scarlet mist causes bleeding that turns into a foaming mist. When a creature under the effects of scarlet mist takes persistent bleed damage from the toxin, creatures within 5 feet take the splash damage. The persistent damage can't be staunched until the poison's effects end. A creature that can't bleed doesn't take the bleed damage or cause the splash damage but can still take the poison damage.
