You deal 100 physical damage and inflict a bleed that does 20 true damage over 3 seconds. It might stack cumulatively, like Draven's old Wicked Blades, or it'll semi-refresh like Varus/Fiora (i.e. It only refreshes if you apply the same or greater, otherwise it doesn't refresh).

It's a well written tooltip - does exactly what it says. It's only unclear how reapplication is handled.
