The Knell Prime is a secondary weapon that was released alongside Harrow Prime and Scourge Prime. He is best known for his deadly headshot potential, rewarding good aim with disgusting damage.
Which relics have Knell Prime components?
Knell Prime components can only be found in three different relics at the moment:
- Meso A3 has the Knell Prime receiver as a silver part.
- Neo K4 has the Knell Prime Barrel as its golden part.
- Axi P4 has the Knell Prime Blueprint as its bronze model.
Along with the two parts and blueprint, players will also need 15 Credits and five Orokin Cells to craft their Knell Prime.
Where to farm these relics

Our suggestion for Meso A3 farming is to spend time on Io (Jupiter) or Helene (Saturn).
Io and Helene are Defense Missions that are popular farming sites for Meso Relics and other resources (Io for Oxium and Helene for Combined Affinity and Orokin Cells). Io is faster because it's a wide open area with a stationary defense target, but Helene is a still fast and valid alternative if you need Affinity Cells and/or Orokin.
You will always receive a Meso Relic on rotation A for Io and Helene. You receive an A spin reward for completing five and ten rounds, so go ten rounds and start again.

For Neo K4 relics, you should go to Hydron (Sedna).
The Defense mission on Hydron doesn't have the highest drop chance for Neo K4, nor does it drop guaranteed Neo Relics like some Disrupt missions. But you will always, always, always find a full group of people to run Hydron with. It's the number one place for Affinity Farming in Warframe, so there are always people running it, which makes it both quick and easy.
Our recommendation is to equip whatever needs leveling and run Hydron. You'll have a decently high chance of getting a Neo Relic as a reward for rounds five and ten. Leave after that, equip new things as needed, and start over as many times as you can for the same mission.

We recommend going to Apollo (Lua) in your Axi P4 relic hunt.
Apollo is a Tier 3 Disruption mission and you will still receive an Axi Relic for earning a Rotation B reward in this mission. You can rack up Axi Relics quickly by forcing the B-spin reward every turn.
To do this, successfully defend all four objectives in the first round, defend at least three of them in the second round, defend only two or three objectives in the third round, and defend only one or two objectives in the fourth round and beyond.
