Captain Vor's shield is nowhere near ordinary, it takes a full magazine or two of MK1-Braton to deprive his shield to damage him. It's best to move on to another weapon with higher DPS like Braton, you should have enough credits to purchase it by this point.
At every change of phase, he will shield himself with his Sphere Shield and summon a squad of Lancers and Butchers to his aid, use your melee to exterminate them to save ammo.
Once Phase 2 begins, he'll start to deploy the Nervos Mines. At this phase, backpedal to long distance when he deploys the mines and try to snipe him with an accurate secondary such as Lato. By the time he throws Mines again, the first ones should have expired, move back to short-medium distance and take him out with your stronger primary such as Braton. Rinse and repeat.
Finally, at Phase 3, he will stop using the Seer and Cronus, using the Orokin Laser instead. At this phase, stay close to cover. Exploit your shoulder sight to hide behind a cover while being able to shoot at him. Keep an eye on his mines, sprint to the next cover when he deploys them.
Utilizing Warframe AbitiliesEdit
Nova's Molecular Prime is not advisable, as Captain Vor's invulnerability is dependent on his animations. Though his shielded state causes him to recharge his shields very slowly, this usually gives enough time to dispatch his reinforcements before attacking him.
- Due to Update 11's Damage 2.0, Captain Vor's health can be damaged through Status effects, specifically Slashing. This can save both time and ammunition, as the weapon provided with this effect can simply rip his health instead of his shields.
- This effect can also speed up Captain Vor's recovery time between summons, if he retains his shields before being downed.
