The Shedu is a secret weapon that was added to Warframe in the Empyrean update. Taking the form of an arm cannon, the pistol encompasses the entire arm of a Warframe and sits on its shoulder. The weapon does not need ammo and will instead reload ammo when not fired. It shoots a beam that does heat damage and causes electrical damage to the area of effect on impact.
To get the Shedu, you will need to complete Erra's Hidden Quest.
How to start the Erra quest
The Erra quest can only be accessed after performing a specific action in a Railjack mission. The first thing you'll need is a Paracesis weapon, which can be obtained from the Chimera Prologue quest. To start the Chimera Prologue, you must have completed The Sacrifice, then visit your quarters in the Orbiter.
You will need to bring the Paracesis to Veil Proxima on the Empyrean Missions star diagram. You will need to have one of the Intrinsic Skill Trees at Rank 7 to access this area.
A Sentient ship will appear on one of the Veil Promima nodes for 30 minutes at a time and will be marked with a flashing red symbol. You will need to find and board this ship, then hunt down a red crystal that it houses. If you destroy the crystal with a Paracesis, you will be able to access the Erra quest from your quarters on the Orbiter. The mini-quest takes place in certain cutscenes, and when they are completed, you'll have a blueprint for the Shedu.
You will also need to use the following parts:
- Baril
- Frame
- Manipulate
- Recipient
These coins can drop from Symbilysts who are on the Sentient Ship in Veil Proxima. To find the sensitive vessel, we suggest using the timer on the Semlar website. Once all the pieces have been cultivated, you can build the Shedu in your foundry. It has a 24 hour build time, which can be skipped for 35 Platinum, Warframe's premium currency.
