This fight takes place in an instance.

On death, all unprotected items will be moved to a grave outside the instance. Any items left on the ground will be lost.

This article has a strategy guide.

All information on mechanics and strategy will be on this page.

The Hueycoatl (/ˈhweɪkoʊˈætəl/ HWAY-koh-at-el^[1]) is a draconic boss whose large body is coiled around the Darkfrost. Said to have scales as strong as rock and asleep atop a pile of gold, the Hueycoatl has awakened and wreaked havoc around the mountain and the dwarves of Cam Torum require assistance in subduing her.^[2]

She can be fought in a group of up to 20 players, or via a private instance by the meeting flag next to the bank buffalo for a fee of 50,000 coins (25,000 with completion of the hard combat achievements). Ironmen are eligible for drops when fought in a group. Though players can solo her, there are parts of the fight that are preferably dealt with in a group.

Uniques from the boss include the tome of earth, the dragon hunter wand, Hueycoatl hide, and huasca seeds, whose herbs are exclusively used to create prayer regeneration potions.

Fight overview[edit | edit source]

Players initially confront five exposed segments of the Hueycoatl's body at the base of the mountain, all the while avoiding the glowing symbols and using the correct prayers to counter her projectiles. Once all segments are defeated, the tail ascends the mountain, clearing the path to the summit.

At the summit, players must attack her head directly, again taking care to avoid glowing symbols and pray correctly. Here, teams of three or more can balance their protection prayers in order to allow the seer to light up the braziers, activating a 30% damage bonus for players. This bonus remains in effect as long as the braziers are lit.

Once players get her to half health, she will shield herself, requiring players to break her tail. The tail is subject to a damage cap of 4 or 9, depending on whether the player's crush attack bonus is their highest, making this phase the longest of the fight for smaller teams. Additionally, the tail will perform a slam attack each time it shifts position, releasing a shockwave that inflicts approximately 25 damage if not evaded.

Once the tail's health is depleted, the Hueycoatl's shield dissipates, allowing players to resume their attack on her. In this final stage, she will continue her standard attacks (glowing symbols and prayer projectiles) with increased frequency, while also employing her tail slam shockwave attack.

Money making[edit | edit source]

The following money making guide is available for The Hueycoatl:

Method	Hourly profit	Skills
Killing Hueycoatl (Solo)	1,336,363	80+ , 90+ recommended 70+ recommended for Piety 76+ recommended for Thralls

Drops[edit | edit source]

In order to obtain drops from the Hueycoatl, the player must deal a minimum of ~75 damage to the head or tail. If the player doesn't do at least ~25 damage to the body, they will receive fewer rewards. The Hueycoatl drops a large lump of items upon death, and the share players receive from it is based on the player's total damage to the Hueycoatl.

The maximum quantity of a drop assumes that the player is soloing.

The MVP, the player who deals the most damage, gets a 10% increase to their drop share.

Drop rates estimated based on 88,030 samples from the Drop Rate Project, unless otherwise cited.
