Form III: Viam Grillus

 (Latin for Way of the Grasshopper), also known as The Form of Agility, is the third of seven forms of Kombat. Grillus is considered the oldest of all seven forms because it was created by the Grand Master Brutus Agathon and the first Conduit and Beta Prime, Yosef Elhafim. It is named as Form III because of its lesser use than the first two forms: Aquilla and Anguis; as Grillus caters to agile Ignitions in the form of daggers and short swords. Developed to address the failings of Form I, Grillus is the most dueling-centric of the seven forms. Relying on precision and efficiency over Aquilla's wild, sweeping motions, Form II allowed an Initiate to defend himself against an opponent with minimal effort, while also heavily avoiding disarmament.

Grillus, described as an elegant and focused form, is based on balance and footwork to outmaneuver opponents. Fluidity and deduction of motion are relied on, rather than strength, with the bladework heavily utilizing jabs and light cuts rather than hack and slash movements.
