Companions are loyal personal allies to the Tenno. They will use their own unique precepts, weapons and abilities to assist their owners in their missions at any cost, even going so far as going directly into harms way to protect them. Companions are not a one-time-use ally gear like Specters, but rather equipped in their own slot in the user's loadout via the Arsenal. Users can only equip one companion at any time. A companion's stats, abilities, and behaviors can be upgraded and manipulated via their own set of mods. Modding companions is similar to modding Warframes.

There are currently seven classes of companions: robotic Sentinels, living Kubrows and Kavats, the modular MOAs, the infested Predasites and Vulpaphylas, and the advanced Hounds. There are many differences between these classes ranging from combat and movement behaviors to acquisition to possible maintenance requirements. Most classes also have their own distinct subclasses, each with dedicated mods and other specifications.


Main article: Sentinels

Sentinels are hovering companions that follow their Tenno masters around and assist in various ways, dependent on the precepts used to program them. It is possible to program sentinels with precepts, or skill mods, that can turn a sentinel into an attack drone or a support drone. Sentinels can also accommodate their own unique stat-increasing Mods, similar to Warframe mods.

Moa Pet.jpg
Main article: MOA (Companion)

MOAs are terrain-restricted companions that can use ranged weapons or perform melee attacks. There are currently 4 MOA Models.

Main article: Hound (Companion)

Hounds are robotic canine companions of the Sisters of Parvos. There are currently 3 Hound Models.


Main article: Kubrow

Kubrows are terrain-restricted melee canine companions. Kubrows behave similarly to NPC allies (i.e. specters) as they will stay within close proximity of the player while fighting alongside them and will enter bleedout states when they are downed, from which they can be revived. Incubated Kubrows have variable permanent traits such as species, height, and eye color, as well as customizable features like fur color and fur pattern. There are currently 6 species of ownable Kubrows, each with different stats and abilities.

Main article: Kavat

Kavats are terrain-restricted melee feline companions similar to Kubrows. They also have different breeds, color palettes, and patterns. There are currently three types of Kavats.

Beasts Infested[]

Main article: Predasite

Predasites are terrain-restricted Infested companions. There are currently 3 subspecies of Predasites.

Main article: Vulpaphyla

Vulpaphyla are terrain-restricted Infested fox-like companions. There are 3 subspecies of Vulpaphyla.

Precept Mods[]

Priority for precept usage (1 is highest priority and 10 is lowest).

In general, precepts are mods which alter the behavior of a Companion, and are effectively the companion's "abilities". Every type of Companion has their own specific precepts that cannot be used by the other type (For example: The Djinn Sentinel cannot use the Helios Sentinel's Mod TT 20px.png Investigator precept). However, there are precepts that are universal within a class of companions. Upon acquiring a companion, the user is automatically granted its respective specific precept mods.

Companions will use their precepts in a prioritized order, where the top left slot is the highest priority and the bottom right slot is the lowest. Precept mods do not need to be installed in the respective polarized slot to be used.

Companions will check to see if the conditions to use the highest priority precept are fulfilled, and will continue to use that precept until the conditions are no longer met. Then they will check each other precept in priority order. Companions will also interrupt the usage of lower priority precepts to use higher priority precepts.[citation needed]


  • Active pet companions can roam and/or follow their owners around the Orbiter, excluding Sentinels, MOAs, and Hounds.
    • They can interact and play with Roller Floofs in the Orbiter.
