How to beat Sprag in Junk Run mission in Warframe

Sprag is a Grineer soldier and mini-boss for the queens. The queens rule the Grineer forces, and their sister Ven’kra is never far from their side. They appear with Veils of Narmer during Kahl’s weekly missions, and you can try hunting them down to complete a challenge and earn 15 stocks for your troubles.

When you start the Junk Run mission, run forward and hack the camera to disable the first gate you come across – run past the deacons on patrol until you see the large open area with a camera for achieve chop. Stick to the left side of this room and head towards the corridor with a gate and a lone Grineer soldier blocking your path.

The white arrow on the map above shows you the right place. Use the Veilbreaker ability on the Grineer Soldier to bring him under your command. Instruct him to destroy the gate to enter the hidden area. Advance in this area and you will come face to face with Sprag.

Sprag has a health bar divided into three segments. Each segment is a different phase for that fight. The first phase is relatively simple. Sprag has a specialized and sizable axe, and will mainly dash at you to try and land a melee attack on you. Sprag can also throw her ax at you from afar; This move can knock you over and leave you vulnerable for up to five seconds.

After the first phase, Sprag becomes immune. In order to destroy the drones that make them immune, you need to find mines scattered around the boss arena. Instruct your Grineer squadmate to activate the mine as a trap. Use yourself as bait and wait next to the mine. Sprag will leap into the air and charge up her ax, and a crosshair will appear under your feet.

As Sprag drops to attack you, the land mine stuns her. While she’s stunned, shoot her two drones. If they are destroyed, they can be damaged again. Repeat the first phase and cut down from afar to bring them to the third and final health bar.

The exact process repeats itself, order your party to arm a mine, wait for it to be stunned, and shoot the drones again. This time, however, you must use your Veilbreaker grenade on them. Complete the mini-game while she is stunned to free her from her bonds. The fight ends when she uses her jetpack and exits the arena.

This will complete the optional Sprag mission and give you 15 shares. This currency can be used to purchase Archon Shards, Styanax Parts, and Weapons.
