The Biting Tongue of clashing blades and the art of cutting. Over the course of a minute, a Faltering speaker can whistle themselves a dagger and a Familiar speaker can sing a fine blade. These must be constantly sung to be maintained. A Fluent speaker has no need for these; they cut with every breath. They can sing melee attacks within audible range, dealing 1d8 damage on a hit.
Learning this Tongue attracts edged weapons to the speaker. Blades will never miss their mark when used against them.
