How to Unlock the Helminth Segment in Warframe

Reach Mastery Rank 8 and Rank 3: Associate with the Entrati on Deimos. Buy the base Helminth Segment blueprint from Son for 15,000 Entrati Standing, craft it in the Foundry, then install it in the Helminth room on your Orbiter. Once installed, the segment opens the system for subsuming eligible Warframes and transferring abilities.

1. Unlock the Entrati and check your Mastery Rank

Complete Heart of Deimos and use the Necralisk hub to work on your Entrati rank. Speak to Mother for bounties and use the family vendors to see which tokens and resources you can earn. Check the rank-up requirements with Mother as you go. The requirements include Standing and can also ask for specific items. Check the list before spending resources on other blueprints.

Mastery Rank and Entrati rank are separate. Check your profile for Mastery Rank and the Entrati menu for your syndicate rank. If you are working on both, you can make progress on Mastery by leveling equipment you have not mastered while completing Deimos activities. If the only thing holding you back is the rank-up test, take it before trying to buy the blueprint.

2. Reach Associate and save Standing for the purchase

1. Earn Entrati tokens through Deimos activities, such as Mother's bounties.
2. Exchange appropriate tokens with Grandmother for Entrati Standing.
3. Meet the rank-up requirements and advance to Rank 3: Associate.
4. Earn or turn in enough additional tokens to have 15,000 Standing available for the blueprint.
5. Open Son's offerings and select Helminth Segment.

The rank itself does not give you the blueprint. Check your balance again after advancing to Associate, since you may need another set of token turn-ins to pay Son. If you hit the daily Standing limit, you can prepare tokens for another day and switch to collecting crafting resources in the meantime.

3. Craft and install the base segment

Return to your Orbiter and open the Foundry. Locate the Helminth Segment blueprint and inspect the recipe. The blueprint purchase unlocks the build, while the Foundry lists the resources and Credits needed to start it. Check that you are crafting the base segment. The Helminth Invigoration Segment and other Helminth upgrades have different functions and requirements.

Start construction when the recipe is ready. Once the build finishes, claim the segment from the Foundry. Go to the Helminth room on the Orbiter and interact to install it. If you crafted it but the system still looks unavailable, check whether the completed item is waiting to be claimed.

4. Check what the system allows before using it

The base segment allows you to subsume eligible Warframes and infuse abilities. Subsuming consumes the Warframe, so use an eligible spare if you still want to play the one you own. Check the displayed ability before proceeding. A Warframe gives the designated ability for that frame, so review the preview before committing one you spent time building.

Check the resource and feeding prompts when you first open the system. The materials you spend to build the segment are separate from the resources Helminth uses later. If you want to try a new ability immediately, inspect what the infusion asks for before consuming a spare frame or spending resources elsewhere.

5. Diagnose a locked blueprint or chair

If Son's blueprint is locked, confirm Mastery Rank 8, Entrati Associate, and your current Standing balance. If you were looking at the Invigoration blueprint, go back and find the base Helminth Segment. That later upgrade has a different rank requirement.

If you bought the blueprint but the chair is unchanged, check the Foundry in this order: whether you started the build, whether it finished, and whether you claimed it. Return to the chair and look for the installation interaction. After the segment is installed, open the Helminth interface and confirm that the ability features are available before you start spending materials.

A practical way to organize the grind is to check three screens before starting another bounty. First check Mother's rank-up requirements so you know which resources to keep. Then check your remaining daily Standing capacity before trading tokens with Grandmother. Finally, open the blueprint or Foundry recipe and note which materials you still need. That lets you choose between earning tokens, gathering resources, and working on Mastery without spending the same evening doing all three.
