Most Warframes in the game have their Signature weapons. In the case of Protea that is the Velox.
The Velox is an automatic pistol with a high fire-rate, solid magazine and decent accuracy. The weapon also has what I consider to be a rather stale gimmick. It does not consume any ammunition every fifth shot. In the hands of Protea it does not consume any ammo every second and fifth shot. This features helps with ammo consumption.
It features a good status chance of twenty two but suffers when it comes to critical stats. Only fourteen percent critical chance and a one point eight critical multiplier which is not fantastic.
The damage on the weapon favors Slash Procs especially if you favor Maim in order to increase the chance of Slash to activate.
