Helminth: unlock it, feed it, swap abilities

Every Warframe has four fixed abilities. With the Helminth you swap one of them for an ability of another Warframe, so a weak Warframe can gain a heal or a damage buff, for example. The Helminth is an Infested creature living in a sealed room on your Orbiter.

The key terms in short:

Segment

A part for your Orbiter that unlocks a new feature. You build it in the Foundry and then install it.

Foundry

Where you build new gear from blueprints and resources.

Standing

Reputation with a faction, earned through missions and bounties and spent at its vendors.

Entrati

The family on Deimos. Son, one of them, sells the Helminth blueprint.

Secretions

The Helminth’s currency. You get them by feeding it resources.

Subsume

You give the Helminth a Warframe, which is consumed. In return it learns one of its abilities.

1. 01

   Play “Heart of Deimos”

   The quest opens the Necralisk on Deimos, home of the Entrati family.

2. 02

   Earn Entrati standing

   Run bounties in the Cambion Drift and trade tokens with the Entrati until you reach rank 3 “Associate”.

3. 03

   Buy the blueprint from Son

   Son in the Necralisk sells the Helminth Segment blueprint for 15,000 standing. You need Mastery Rank 8.

4. 04

   Build it in the Foundry

   It costs 50,000 credits, 5× Purple Velocipod Tag, 20× Adramal Alaşımı, 5× Doymuş Kas Kütlesi and 15× Ganglion, and takes 24 hours.

5. 05

   Install it

   Install the finished segment on your Orbiter. The door to the Helminth room opens.

Everything at the Helminth costs secretions. There are six kinds: Calx, Biotics, Synthetics, Pheromones, Bile and Oxides. You get them by feeding the Helminth resources, and almost every resource in the game can be fed.

• A green arrow means the Helminth likes that resource right now: up to 30% of a secretion bar.
• A red arrow means it has had enough of it, and the resource gives only a few percent.
• Each bar caps at 100%. Anything above is wasted, so never overfeed.
• Its appetite recovers over time. Feed many different resources instead of a lot of one.

When you subsume a Warframe, you sacrifice it for good. In return the Helminth learns one fixed ability of that Warframe, which you can then give to any other Warframe.

• Only regular Warframes, no Prime or Umbra versions.
• It does not need to be rank 30. Level it first anyway, or you miss its mastery points.
• Subsuming takes 23 hours, and only one Warframe at a time.
• Each Warframe can be subsumed once and always gives the same ability. Passives cannot be subsumed.

Popular first picks:

Ability	From	What for
Roar	Rhino	More damage for the whole squad
Nourish	Grendel	Energy and Viral damage
Gloom	Sevagoth	Slows enemies and heals you
Pillage	Hildryn	Strips shields and armor
Xata’s Whisper	Xaku	Void damage on your weapons

Sit in the chair with the Warframe you want to change and pick a learned ability. It replaces one of the Warframe’s four abilities.

• You can replace one ability per mod configuration. Different configurations may carry different abilities.
• An ability always sits in the same slot in every configuration.
• You can undo it any time, but the secretions you paid are not refunded.
• Roar, Eclipse and Xata’s Whisper can only replace a Warframe’s own damage buff on Warframes that have one, such as Chroma or Octavia.

Feeding, subsuming and infusing give the Helminth experience for its Metamorphosis rank. New ranks raise how many abilities it can hold and unlock its own Helminth abilities, such as Empower for more ability strength.

• Invigorations: Every week the Helminth offers three random Warframes a seven-day offense and utility bonus. You need the Invigoration segment: its blueprint costs 30,000 standing at Son and needs Entrati rank 5 and Mastery Rank 8.
• Archon Shards: With the Archon Shard segment from the quest “Veilbreaker” you socket permanent bonuses into your Warframes. Everything about them is in the Archon Shards: unlock, farm and socket them tutorial.
