Built by the Grineer for their elite troops, the Vulkar is a devastating distance weapon. In the right hands it is capable of taking down targets long before they get into attack range.
The Vulkar is a Grineer sniper rifle, released in Update 8. It is equipped by Grineer Ballistas. It mainly utilizes Impact damage and shares the highest status chance of sniper rifles with the Lanka, making a good amount of the shots to deal devastating procs.
It can be closely compared to the Vectis, a Tenno sniper rifle.
Use the Sniper Ammo Mutation mod to greatly relieve the low total ammo and ammo drop chance for sniper rifle ammo.
Rupture is the most effective physical mod to use, as it increases Vulkar's already decent impact damage further.
Heavy Caliber can be used on the Vulkar with little noticeable effect on its long-range accuracy, as its slow rate of fire ensures that its shots will always land on its crosshair. Heavy Caliber will affect the spread of additional bullets created by Split Chamber however.
It seems the Vulkar is based-off on the name "Vulcan", the god of fire, the forge and the volcanoes in Roman mythology.
It would seem that the Vulkar has an exceptionally high Impact damage for a sniper rifle, suggesting that it uses powerful slug rounds, despite its depiction as an armor-piercing rifle.
