Oblation: Bloodline
Drops: Cull's Shadow (Kinetic Fusion Rifle — Weapon of Sorrow)
More than half of this mission is platforming and basic puzzle-solving. The boss fight uses a brazier-dunking loop.
How to Unlock
This is a secret, unmarked questline. To unlock it: (1) Have a Weapon of Sorrow in your inventory. (2) Launch the Scarlet Keep Strike from the Moon destination. (3) Complete the strike as normal until the final boss area. (4) Look for a new room inside the Temple of Crota — interact with the Hive runes to start the questline. Complete the rune steps to unlock the Oblation: Bloodline mission node.
You must have a Weapon of Sorrow equipped or in your inventory to trigger the unlock. Any Hive-themed Weapon of Sorrow works (Thorn, Osteo Striga, Touch of Malice, etc.).
Section 1 — Sabotage the Drilling Operation
Disable a massive Cabal energy drill through a series of destruction tasks.
(1) Defeat the shielded Centurion guarding the command console. (2) Flip the Safety Controls switch. (3) Destroy three fuses behind the switch. (4) Shoot the vents on cooling pillars when they're open and glowing hot — this destroys each cooling pillar. (5) Repeat at a second location with three additional fuses. (6) Enter the command center and flip the final switch to overload the laser drill. (7) Take the man cannon into the hole the drill created.
The cooling pillar vents only open for a brief window. Watch for the vent flaps opening and immediately shoot inside — you won't have long.
Section 2 — Platforming Ascent
Two extended vertical climbing sections through Hive tunnels.
Use Acolyte enemy positions as waypoints — they mark every platform and ledge you need to hit. In the first area, jump up into the light green cave on your left and follow Acolyte positions through stalactites and tunnels to the Soulfire Crux area. In the second area, use hanging sarcophagi and rock ledges to ascend. Jump through the hole in the stairs when you reach it.
Falling in the platforming sections respawns you at the last checkpoint but costs time. No wipe mechanic here — just patience.
Section 3 — Extinguish the Soulfire Barrier
Multi-phase encounter requiring Soulfire Charge buffs to light three braziers.
(1) Destroy the Pyre Matron Wizard. (2) Punch the Soulfire Vessel Thrall (melee it) to gain the Soulfire Charge buff. (3) Carry the buff to an unlit brazier and dunk it (interact with the brazier). (4) Clear the spawning enemy room, including three Pyre Matrons. (5) Punch the central Vessel and dunk in the second brazier. (6) Navigate to the back left tower (Acolytes mark the path). (7) Defeat the Ogre and all enemies in the final room. (8) Punch the final Vessel and dunk in the last brazier to clear the Soulfire Barrier.
The Soulfire Charge buff has a timer. Move to each brazier immediately after dunking — don't stop to fight enemies while carrying the buff unless you have no choice.
If the Soulfire Charge buff expires before dunking, you have to restart from the Pyre Matron kill for that brazier. Keep moving.
Boss — Valus Tau'Rig, The Insatiable
Final boss with a minimal health phase, followed by a repeating immunity/damage loop.
Deal initial damage using Power ammo, Praxic Blade, or rockets. This phase has minimal health — burn through it quickly.
(1) Three Pyre Cantors (powerful Wizards) disappear and reappear, each guarding a Soulfire Vessel. (2) Watch them fly to their positions. (3) Defeat all three Cantors. (4) Punch/melee the Soulfire Vessel to claim the Soulfire Charge buff. (5) Dunk the buff in a brazier to stun Tau'Rig and remove his immunity. (6) Deal heavy DPS immediately. (7) At 50% health, additional Ogres spawn — clear them while continuing the Cantor kill loop.
Assign one player to watch Cantor flight paths — they spread out fast and need to be killed before they re-shield the Vessel. Rockets and burst damage work best. Save a Super for each damage window.
Missing a Cantor means the Vessel stays shielded and Tau'Rig stays immune. Don't start the Vessel melee until all three Cantors are dead.
Running out of DPS windows repeatedly without killing Tau'Rig — enrage wipe (limited total immunity cycles before the boss enrages).
Catalyst — Soulfire Succor (Post-Mission)
After defeating Tau'Rig, equip Cull's Shadow and return to the first encounter area without leaving.
(1) Clear all remaining enemies. (2) Navigate to the third brazier location (back left tower). (3) Jump across the sarcophagi. (4) Interact with a floating Hive grimoire — it reveals runes. (5) Shoot the runes on the boss room door in order from top to bottom. This unlocks the Oblation: Soulfed follow-up mission which grants the Soulfire Succor catalyst for Cull's Shadow.
