Collect three Glands from the three Corrupted Gates in the southern map region: Depleted Gland, Thawed Gland, and Faded Gland. Each gate holds exactly one. After securing all three, activate Night Mode, travel to the Forgotten Tower, and locate the night-only NPC. Trade all three Glands to receive the Seedbeater’s Scripture, an equippable item that directly weakens the final boss encounter.
Where I Start: The Three Corrupted Gates
I treat the Corrupted Gates as the only real progression blocker in this quest line. They cluster in the southern section of the map, and each one contains precisely one Gland. There is no RNG involved — entering all three gates guarantees all three Glands. 
Depleted Gland
Thawed Gland 
Faded Gland
| Gland | Location | Notes |
|---|---|---|
| Depleted Gland | Corrupted Gate #1 | First gate I enter |
| Thawed Gland | Corrupted Gate #2 | Second gate on the route |
| Faded Gland | Corrupted Gate #3 | Final gate, southernmost position |
I recommend clearing these gates before tackling any optional content. The Glands themselves are special items — they do nothing on their own, but they unlock the real reward once the quest chain completes.
Note: Each Corrupted Gate locks after you leave. I make sure to grab the Gland before exiting, or I’d have to re-enter the entire gate.
What I Do After Collecting All Three Glands
The Glands are a means to an end. The actual payoff — the Seedbeater’s Scripture — comes from a hidden NPC interaction. Here is the exact sequence I follow:
- Collect all three Glands from the Corrupted Gates.
- Activate Night Mode — this is mandatory; the NPC does not appear during daytime.
- Travel to the Forgotten Tower.
- Locate the secret NPC — only visible at night in this area.
- Offer all three Glands (Depleted, Faded, Thawed) to the NPC.
- Receive the Seedbeater’s Scripture as a reward.
- Equip the Scripture before the final boss fight.
The Seat Eater Scripture is an equippable item, not a consumable. Once equipped, it modifies the final boss encounter in your favor. I slot it before entering the boss arena and never swap it out mid-fight.
How I Activate Night Mode Without Wasting Time
Night Mode is a prerequisite for the Forgotten Tower NPC, so I handle this before anything else. The activation path is specific:
- Pick up the Gloom-Bound Flame — located next to the first beacon in Fallgrim.
- Carry it to Marrow Keep — the flame persists in your inventory until used.
- Interact with the beacon at the top of Marrow Keep to trigger Night Mode.
The system is fully reversible. I can toggle back to daytime at any moment, which matters if I need to farm lower-difficulty enemies or revisit daytime-only areas.
If you need the full Night Mode unlock breakdown, you could use the Mortal Shell 2: How to Unlock the Night Mode guide.
Warning: Night Mode globally increases enemy difficulty. If I’m under-leveled, I activate Night Mode only when I’m ready to head straight to the Forgotten Tower.
Night Mode Trade-Offs I Account For
Since Night Mode is required for this quest, I factor in its global effects before committing:
- Enemy difficulty increases — all enemies hit harder and take more punishment.
- Rewards scale up — Gloom and Gold Coin drops increase proportionally.
- Toggle is free — I can enable or disable Night Mode at any time, no penalty.
For this specific quest, the reward bump is incidental. I’m here for the Seat Eater Scripture, not the farming bonus. But if I need Gloom or Coins anyway, I combine the quest run with a farming session to maximize efficiency.
Why the Seedbeater’s Scripture Matters for the Final Boss
The Scripture is the single most impactful item I can bring into the final encounter. It does not require additional quest steps, does not consume resources, and provides a passive advantage that persists for the entire fight.
I consider this quest mandatory before attempting the final boss. Skipping it means fighting the boss without the Scripture’s benefit — a self-imposed handicap that serves no purpose. The total time investment is modest: three gates, one night toggle, one NPC conversation.
