How to Beat the Zealoid Prelate in Warframe (2026): Arlo’s Flame, Exequias and Pathocyst Parts
Exequias, Deimos: kill a Bastion, carry the flame, break the invulnerability
Last Updated on September 30, 2026
The short answer
The Zealoid Prelate is a normal Assassination node on Deimos now, so no Zealot Derelict Code is needed. The fight turns on the lantern: at half health it goes invulnerable, and you break that by killing a Zealoid Bastion and carrying Arlo’s Flame to it. It drops Pathocyst parts.

The fight, step by step
- Pick Exequias on Deimos. No code is required.
- Damage the Prelate until it reaches half health. Bring Slash or Heat and something with area damage.
- It becomes invulnerable. Find and kill a Zealoid Bastion.
- Pick up the lamp with Arlo's Flame that the Bastion drops. Its light removes invulnerability inside the radius.
- Carry it to the Prelate and fight inside the light. You cannot use a primary weapon while carrying it, so use secondary or melee.
- The light shrinks with time. Killing Infested inside the radius makes it bigger, so keep killing.
- Damage it until it breaks the lamp and links to the nearby Infested to heal. Kill the linked Infested and repeat until it dies.
What it drops
| Drop | Chance |
|---|---|
| Pathocyst Blade, Pathocyst Blueprint, Pathocyst Subcortex (each, one per run) | 33.33% |
| North Wind, Fever Strike, Molten Impact, Eleventh Storm, Shocking Touch (each) | 18.33% |
| Target Acquired, Tempo Royale, Spinning Needle (each) | 2.78% |
Tips that save runs
- The Zealot Derelict Codes came from Nightwave Series 2, by finishing Infestation Outbreak missions. They are retired.
- Large area weapons handle the Infested crowd around the lamp.
- Do not chase the lamp radius out of position. Fight from inside the light.
Mistakes that waste runs
- Trying to burn it down while invulnerable.
- Carrying the lamp and switching to a primary weapon that will not fire.
