To defeat the Obsidian Wyrm in RuneScape: Dragonwilds, you must complete the “Brink of Extinction” quest. This quest, which is unlocked by speaking to Zi in the Burning Spire area of the Umbral Sands region, ultimately rewards you with the ability to craft the Obsidian Cape, which is implicitly tied to the KotHaar, creatures that wrap themselves in layers of magma and obsidian.
Quest Prerequisites
The “Brink of Extinction” quest is a crucial step in understanding and, by extension, overcoming the challenges posed by the Obsidian Wyrm. While there are no explicit combat requirements stated for the wyrm itself, the quest tasks involve various activities across the game world. It’s recommended to have a good understanding of fishing and general exploration to efficiently complete the objectives. The quest is initiated by speaking with an NPC named Zi.
Brink of Extinction Walkthrough
The “Brink of Extinction” quest begins by speaking to Zi in the Burning Spire, located in the northern section of the Umbral Sands region. It is highly advisable to install a Loadstone near Zi’s location for quick travel, as you will return to him after completing each objective. The quest involves several distinct objectives.
The first objective requires you to gather specific provisions. You will need one Cactus Steak and three Raw Beltfish. Cactus Steaks are obtained from bunny-shaped, Y-shaped cacti, commonly found in the Alcarrid Oasis. Raw Beltfish can be acquired by fishing in any river or lake using a Yew-Road with Kalphite Bait. Kalphite Bait is crafted from one Feather, one Desert Thread, and one Kalphite Ichor. After collecting these items, return to Zi to receive your next task.
The second objective involves interacting with four pedestals within the Gauntlet of Fire. Your goal is to approach and interact with each pedestal to extinguish the fire emanating from them. The exact locations of these pedestals will need to be discovered within the Gauntlet of Fire area. Once all four pedestals have been touched, report back to Zi for the final stage of the quest.
The final objective is to enter the Cave of Screams using a specific password. The quest log or Zi will provide the necessary password to gain entry. The exact location of the Cave of Screams is not specified in the available information, but it is implied to be within the Umbral Sands region. Successfully entering the cave will complete the “Brink of Extinction” quest.
Crafting the Obsidian Cape
Upon successful completion of the “Brink of Extinction” quest, you will be rewarded with the Plate of Pure Obsidian vestige. Studying this vestige unlocks the recipe for the Obsidian Cape at an Armour Bench facility. The Obsidian Cape is a basic item that provides a small boost to Defence stats. It is described as being black as cooled lava and radiating a faint, lingering heat. The cape’s lore indicates it is made from the carapace of a KotHaar, like Zi, who do not feel pain or loss when their outer layers are taken.
The Obsidian Cape offers the following combat stat bonuses:
| Stat | Bonus |
|---|---|
| Melee Defence | +4 |
| Ranged Defence | +4 |
| Magic Defence | +4 |
The cape itself requires no materials to craft once the recipe is unlocked. Its creation is a symbolic representation of your interaction with the KotHaar and their unique biology. While the cape itself doesn’t directly “defeat” the Obsidian Wyrm in a combat sense, the entire “Brink of Extinction” quest line and the subsequent crafting of the cape are the established method to interact with and resolve the Obsidian Wyrm narrative as of June 22, 2026.
