RuneScape: Dragonwilds Sacred Oil: Recipe, Farming Routes, and Tier 5 Crafting Uses

The Fellhollow keeps its dead busy. Hunting Rotsworn corpses and the reanimated undead drops the ingredients for Sacred Oil, the keystone resource for late-game crafting. This guide breaks down the recipe chain, where to grind for each component, and which Tier 5 gear you can build once the bottles start stacking up.

Brewing Sacred Oil

Sacred Oil arrived with the Fellhollow Update and is mixed at the Brewing Cauldron. One vial costs:

• 3x Ectoplasm
• 3x Necrotic Bonemeal
• 1x Clay Vessel

None of those ingredients drop ready to use. The full materials pipeline looks like this:

• Clay Vessel: refine raw Clay into Clay Vessel (Unfired) at the Pottery Wheel, then fire it.
• Necrotic Bonemeal: loot Undead Bone from the reanimated dead across the Fellhollow, then grind 3x Undead Bone into 1x Necrotic Bonemeal at the Grindstone.
• Ectoplasm: farm Withered Heart drops from Rotsworn enemies in the Fellhollow, then refine 3x Withered Heart into 1x Ectoplasm at the Kiln.

Doing the math, every single bottle of Sacred Oil eats 9x Undead Bone, 9x Withered Heart, and 1x Clay. Plan farming trips with that ratio in mind, especially if you intend to deck out a full armor set.

Edna's Quest and Ulv's Longbow

West of Emberwood Village sits Edna, the NPC trapped inside a mirror who clearly has the worst commute in the game. She offers a three-part quest that requires:

• 1x Sacred Oil
• 1x Silver Bar
• 1x Fine Thread
• 6x Soul Fragment
• 1x Dragon Blood

Finishing the chain unlocks Ulv's Longbow and its recipe, which is reason enough to keep a spare vial in the stash.

Farming Tips Worth Repeating

A few habits keep the grind tolerable:

• Clear Fellhollow zones on a circuit so Rotsworn and undead respawn rotations line up, doubling Withered Heart and Undead Bone yields per loop.
• Stack Clay early. The Pottery Wheel and Kiln are slow stations, so prep Clay Vessels and Ectoplasm in batches between hunts instead of one at a time.
• Park the Brewing Cauldron near your other refining stations so the final mix does not turn into a walking simulator.

Once the supply chain is steady, Sacred Oil stops being a bottleneck and becomes the lever that pushes a character squarely into Tier 5 territory.
