The PROVA is a melee weapon that delivers a high-intensity shock to its target.
The Prova is a Corpus melee weapon unlockable through Energy Lab Research in the Dojo that are commonly used by the Prod Crewmen. Though similar to the "shock prods" that the Grineer Flameblades use, it is slightly larger and more solidly built.
On Jump attacks, the Prova releases six small streams of electricity that each travel outward lead by a sparking orb. This purely cosmetic effect is not shared with other pure Electricity type melee weapons like the Plasma Sword, Lecta and Serro. This effect however is shared with the Amphis, which only deals Electricity status proc on its jump attack.
Prova is Italian for "evidence" or "proof", which in turn is derived from its Latin equivalent proba.
