—In-game description

The Baro Void-Signal is a one-time use Key item, which unlocks a special mission node in the Void called "Void Raider". Baro Ki'Teer sells it for PrimeBucks.png 100 and Credits64.png 25,000 only to a player with InarosPrimeIcon272.png Inaros Prime equipped.

The mission, which can also only be accessed with Inaros Prime, is a 10 wave Defense against level 20-30 Grineer Nightwatch Corps enemies with Baro Ki'Teer as the defense objective, similar to Operatives. Unlike Operatives, Baro is armed with an Aklex.png Aklex and cannot be given a weapon, and has higher health at the cost of not being able to enter bleedout, causing the mission to fail instantly if his health reaches 0.

The mission rewards a guaranteed Desert Skate Specter and one reward in this order (tracked separately for each player):

Once a player has obtained all 5 rewards, they will only receive the Desert Skate Specter from subsequent completions.


  • The Void-Signal is only available in Baro's inventory once per visit (including his full TennoCon Relay offerings), thus additional copies can only be purchased every two weeks.
  • Only the player starting the mission will lose their key on mission completion.


  • Activating the defense lasers is ill-advised as they can instantly kill Baro.
  • Consider using Specters to bypass the Warframe restriction and to help increase your damage output. The best Specter to take to this mission would be a Warframe that has strong support abilities such as TitaniaIcon272.png Titania or OctaviaIcon272.png Octavia.
  • Abilities that can heal an entire party are a must for this mission. For this reason, heavy use ofScarabSwarm130xDark.png Scarab Swarm will make this easier, especially considering that Scarab Swarm can make short work of enemies that are clumped together, while also healing both Inaros and Baro.
    • Infusing Gloom130xDark.png Gloom onto Inaros Prime and using an Ability Range-based build can trivialize this mission, as not only are enemies slowed significantly, Baro and Inaros Prime can heal themselves simply by attacking enemies within range of the aura.
    • Another good infusion would be BloodAltar130xDark.png Blood Altar, as it provides extra healing for both Inaros Prime and Baro, while also taking more dangerous enemies out of the fight so that you can deal with them later.
  • Given Inaros Prime's natural tankiness, he can easily replace the energy consumed with Mod TT 20px.png Rage and/or Mod TT 20px.png Hunter Adrenaline. To further ensure Baro's safety, Inaros Prime can equip Mod TT 20px.png Guardian Derision to redirect incoming attacks to himself, in turn fueling his Energy reserves with the previously mentioned mods and sustaining Energy-intensive abilities such as ScarabSwarm130xDark.png Scarab Swarm more easily.
  • It is advisable to bring in a weapon that deals large amounts of DPS to large crowds such as Ignis.png Ignis or IgnisWraith.png Ignis Wraith, especially with decent punch-through. Alternatively, if you have access to the Archgun Deployer, then a Mausolon.png Mausolon or Cortege.png Cortege with an Orokin Catalyst installed would be good choices to take to the fight considering the former's radial damage and the latter's flamethrower-like properties.
  • Be careful when selecting the mission, as it has a Steel Path version, with enemies level 120-130.


  • The mission name "Void Raider" is a pun on both "Tomb Raider" and "Void Trader".
  • While the item icon depicts Baro wielding DualCestra.png Dual Cestra, he actually uses an Aklex.png Aklex during the mission.


  • The Lotus will chime in (despite not being involved in the mission), and both will say generic Defense mission lines as well as acting as if Baro is a Rescue target.
