WHERE & HOW TO FARM
Check the Holy Bulwark for Large Deralium Shards
Manse of the Hallowed Brothers, outside Brother of Jeremiah’s Vestige; leave by the nearby exterior door and locate the roaming Holy Bulwark.
Before you go
- Reach and activate Brother of Jeremiah’s Vestige in the Manse of the Hallowed Brothers.
- Have a build that can safely defeat the nearby Holy Bulwark or retreat back to the Vestige.
- Check Gerlinde’s upgrade interface and confirm a weapon currently calls for Large Deralium Shards.
Farming steps
- At Gerlinde’s forge, inspect the intended weapon and write down the exact Deralium tier its next upgrade requires.
- Travel to Brother of Jeremiah’s Vestige and rest if you need a fresh attempt or restored healing.
- Leave through the exterior door beside the Vestige and find the Holy Bulwark on the nearby route.
- Engage from a safe position and defeat the Bulwark without being pulled into a longer area fight.
- Inspect the drop and inventory; count only a Large Deralium Shard actually received.
- Return to Brother of Jeremiah’s Vestige. If you are continuing, rest and repeat the short Bulwark attempt.
- Once you have the listed quantity and Vigor, return to Skyrest Bridge and apply the upgrade at Gerlinde’s forge.
- The Bulwark is a chance-based source according to the farm reference; do not assume every kill yields a shard.
- If the forge asks for a different tier, stop this route and use the guide matching that material.
Repeat, collect and use
Repeat the nearby enemy attempt while it remains useful and manageable; drops are not guaranteed. Resting at the Vestige resets standard enemies, not a promise of a particular item.
Common mistakes
- Confusing Large Deralium Shards with Deralium Chunks: they are different upgrade tiers.
- Taking the drop route without confirming the weapon’s requirement: check the forge first.
- Continuing when the Bulwark is too costly to defeat: Gerlinde’s stock and fixed pickups are alternatives for material planning.
When to stop or switch
Stop when you have the amount Gerlinde’s interface requests, or when the attempt is too risky or no longer a useful source for your weapon tier.
