No bleedout, no revive, no healing
Every assumption you have about keeping a unit alive fails with a Necramech.
It does not enter bleedout. When health reaches zero, it explodes immediately. There is no downed state, no crawl timer, no revive prompt. The mech is simply gone for the rest of the mission.
It cannot be healed by Warframe abilities. A Trinity, a Wisp, an Oberon — none of them can restore a Necramech’s health directly. The mech is not a Warframe and does not accept Warframe support.
What does work:
- Health and Energy Orbs, dropped by enemies, the environment, or Warframe abilities that spawn them.
- Bonewidow’s Meathook, which is the mech’s own ability rather than an external heal.
- Ancient Healer Specters, at roughly 30 health pulses.
That list is short, and every entry is either self-generated or a consumable. There is no support build that keeps a mech alive.
The consequence changes how you should play it: a Necramech is not a durable platform you hold ground with, it is a burst resource. Deploy it, do the thing, and expect it to end. Treating it like a tank means watching it explode while your healer frame does nothing.
The four components, and where they come from
A Necramech is not one build. It is four:
| Component | Built from |
|---|---|
| Casing | Damaged Necramech Casing |
| Engine | Damaged Necramech Engine |
| Capsule | Damaged Necramech Capsule |
| Weapon Pod | Damaged Necramech Weapon Pod |
Father in the Necralisk grants the blueprints after Heart of Deimos is completed. The Damaged parts come from two sources: purchased from Father, or dropped by defeating Necramech enemies in the Cambion Drift.
So the grind has two halves. The blueprints are quest-gated and free; the Damaged parts are either farmed from mech enemies or bought. Buying is faster and costs standing and resources; farming is slower and drops other Deimos materials along the way.
Build all four in parallel. The Foundry has no parallel-build limit, so there is no reason to sequence them. The crafting guide covers the queue mechanics.
Deployment and the Gravimag
A Necramech is summoned in mission using a Gravimag, which is the deployment system rather than a weapon attachment. Once summoned, it carries its own weapons and regenerating ammo, similar to Archwing space missions.
It arrives with rank 0 stats and no mods, though all of its abilities are at max rank. That means an unmodded Necramech in a high-level mission is not a damage dealer — it is an expensive way to die. Mod it before you rely on it, using the same capacity and polarity logic as any weapon.
Its default weapon is an unmodified Mausolon. That is functional, not impressive; the mech’s real damage comes from modded weapons and from the abilities.
Voidrig versus Bonewidow
Two mechs exist, and they differ in one structural way.
Voidrig has no equippable melee weapon. It uses arm swipes (Pugil) and aerial ground slams instead. Its identity is artillery: ranged damage, area control, and the ability to hit things the mech cannot reach. For most players this is the easier first build, because it does not require you to close distance in a machine that explodes on death.
Bonewidow has an exalted melee weapon called Ironbride. That gives it a real melee kit including the Meathook ability, which is also one of the few ways to restore its own health. It is the more demanding mech, because melee range on a unit that cannot be revived is a genuine risk.
Pick Voidrig first unless you specifically want the melee playstyle. The mech that stays at range survives longer, and survival is the mech’s whole problem.
Where a mech earns its slot
Be honest about this: Necramechs are not a general-purpose upgrade. They are narrow tools.
Cambion Drift content. The mech is native to Deimos and several activities there assume it. The open worlds guide covers the Deimos loop.
Necramech-required objectives. Some mission types and bounties want a mech specifically, and there is no substitute.
Heavy weapon deployment. The Gravimag path overlaps with Archgun usage, which matters for players building toward heavy weapon builds in normal missions. The Archwing guide covers the related system.
Mastery. A Necramech awards 6,000 mastery at rank 30 and 8,000 if taken to rank 40 with five forma, which is the highest single-item mastery value in the game. The mastery rank guide explains why that is worth more than it looks.
What it is not for: general mission clearing. A Warframe is faster, more mobile, healable, and revivable. Bringing a mech to a normal mission is choosing a worse tool for the job.
Modding priorities
Since the mech cannot be healed, defensive mods are not optional:
- Health and armour — the mech has no bleedout buffer, so every point of effective health is the difference between finishing the objective and exploding.
- Ability strength and efficiency — the mech’s abilities are its damage and its only self-sustain.
- Weapon mods — the mech’s guns are the reason to bring it. Mod the weapon, not just the frame.
- Mobility last — a Necramech is slow by design and mods do not fix that.
The mods guide covers the underlying capacity system, and damage types covers what to put on the weapon. Note that the Steel Path’s enemy level bonus is halved for Archwing and Railjack content — Necramechs do not get that discount, which is another reason to keep them out of high Steel Path nodes. The Steel Path guide covers the modifier list.
