Captain Vor

Captain (formerly Admiral) Vor is the first boss in WARFRAME that players will encounter and is one of the few figures in the game that understands ancientOrokin technology, capable of utilizing it and merging it with Grineer technology to create offensive weapons such as his trademark Seer pistol and his armor, which is powered by a Void Key and grants him a powerful ranged beam attack. Captain Vor can be encountered in three locations currently, making him the most recurring boss beside assassins. First appearing on Mercury and thus being the first boss that players must fight, he then appears again, somehow fully alive, on Ceres as a dual boss battle alongside Lieutenant Lech Kril, then appearing later yet again as a Corrupted version of himself within the Void

Tips

Since he is 75% weak against Viral, Magnetic, Radiation, the most optimal build is to have at least one of each weapon in your arsonal deal one of each type of combine element damage if you want to effectively kill Vor fast. If you're a new player, fighting him will be challanging without these damage type mods, i recommend joining a clan and asking other high leveled players to help you if you're struggling to fight him solo. If you're planning to farm him and you have these damage type mods i would recommend to go excaliber with the exalted blade build. This way you can deal not just the melee status damage but also the Exalted Blades power damage allowing you to kill Vor quickly, just note that in the build, Exalted blade shares your equiped melee weapon's mods and stats.

If you plan on playing with others, best Frame to use is Oberon for that Crowd control and to also heal when needed. most players oppose to Oberon but with the build that i (Moesashi_Shirayuki) have Oberon is the perfect crowd controlling type that can deal radiation against Vor and other grineer that he can spawn, Oberon is good for this because he can heal you if you get low on health. Another alternate healer is Trinity, normally the EV built for Trinity is specifically for Energy Vampire, but using the EV build is good enough for her Blessing ability for quick instant healing incase you get too low of health. A third option of frame for this is Rhino. With Rhino, you can use Iron skin thus not needing to worry too much on being healed, if you have someone as an EV trinity and you go headstrong into Vor with Melee, that trinity could give limitless energy so you can keep using ironskin if Vor takes it down Quickly. though if you solo Vor, Rhino with Ironskin would be good if you have a very optimal build for your melee. Other than that i highly recommend playing with others to take him down unless you're confident on taking him on solo or if you're playing volt since he has a passive ability to charge extra damage based on movement.
