Monster Hunter Wilds Gogmazios Guide: How to Beat the Siege Boss
Complete Gogmazios siege strategy for Monster Hunter Wilds. Phase breakdowns, Dragonator timing, weak points, and group coordination for the only Elder Dragon in the game.
The Only Elder Dragon
Gogmazios is the only Elder Dragon in Monster Hunter Wilds. No Teostra, no Kushala Daora, no Fatalis. Capcom put everything into a single fight added in Title Update 4, and the result is the closest thing Monster Hunter has done to a raid boss.
This is a 4-player siege. You can attempt it solo, but the mechanics assume a coordinated team. SOS matchmaking fills slots quickly — Gogmazios is the most popular endgame quest. HR 100+ required. If you’re not there, farm Tempered monsters first. Check our endgame guide for the fastest route.
Gogmazios is weak to Fire. Cannot be trapped. Elder Dragon rules — no traps, no capture.
What Makes This Different
The arena is a fortified citadel with siege emplacements along the walls: cannons, ballistae, and the Dragonator. These are not optional flavor. Siege weapons deal damage numbers individual hunters can’t match, and some of Gogmazios’s mechanics are specifically designed to be countered with siege tools.
Phase One: The Approach
Gogmazios starts distant and drags itself forward, attacking with its upper body while crawling.
Tar Spit — Three globs in a fan pattern. Tar pools linger and slow your movement. Claw Slam — Overhead forelimb strike. Wide impact zone. Tail Sweep — Catches flankers repositioning behind it.
This is your siege weapon phase. Two players on cannons, two on direct combat. Cannon shots to the head build stagger. Enough hits before it reaches the arena center triggers a knockdown. Ballista operators should target wings to limit aerial ability in Phase Three.
Phase Two: Engaged Combat
Gogmazios reaches arena center and becomes fully mobile.
Body Press — Lifts front half, crashes down. Ground tremor extends beyond the visual slam. Run sideways.
Tar Stream — Sweeping beam of liquefied tar with lingering ground effects. Dodge through it, don’t try to outrun the arc.
Double Stomp — Two consecutive leg stomps with tremor hitboxes. Tremor Resistance helps, otherwise time your rolls.
Wing Buffet — Wind pressure pushes hunters back. Minor damage, but getting shoved into tar pools is the real threat.
Keep rotating to siege weapons when Gogmazios targets someone else. At least one hunter should be on siege weapons at all times. Cannon shots during this phase build toward the knockdown that opens Phase Three.
Phase Three: Airborne
Below 40% health, Gogmazios flies. The tar on its wings heats up and creates lift.
Tar Bombardment — Carpet bombing of heated tar. Sprint to arena edges where coverage is lighter.
Diving Charge — Picks a target, dives full-length across the arena. Sprint perpendicular. Don’t stop until it passes.
Airborne Tar Stream — Beam from above sweeping the full arena width. Get behind stone barricades.
Your priorities while it’s airborne:
- Dragonator — Fire it when Gogmazios passes the spear’s position. Grounds it immediately
- Ballista focus fire — Wing shots cause a stagger that brings it down
- Stay alive — Aerial phase carts more hunters than anything else. Dodge clean and wait
The DPS Check
Below 15% health, the tar ignites. You have roughly 90 seconds to deal enough Fire damage to stagger Gogmazios. Fail, and a tar explosion covers the entire arena. Party wipe. No exceptions.
This is a hard wall. If your team brought Ice or Thunder, you will not pass. At least three of four players need Fire element active.
How to pass it:
- Swap to Fire weapons on your Seikret the moment tar ignites
- Focus Fire damage on head and chest (highest Fire hitzones)
- Fire the Dragonator if off cooldown — its damage counts
- Cannons don’t count. Only player elemental damage and Dragonator contribute
- Pop Demon Drugs and Might Seeds. Every point matters
Playing safe during the check is paradoxically the riskiest option. Go in hard.
Group Roles
Cannon Operator — Manages cannons throughout. Builds stagger faster than anything else. Hunting Horn players fit well, buffing the team between loads.
Ballista Specialist — Targets wings in Phases One and Two, anti-air in Phase Three. Natural fit for Light Bowgun players.
Frontline DPS — Two melee players on wounds and consistent damage. Great Sword and Hammer for burst during knockdowns.
Healer/Flex — Wide-Range Sword and Shield. Keeps the team healthy through tar chip damage, handles Dragonator timing.
Common Mistakes
Ignoring siege weapons. Four melee players hacking ankles while cannons sit empty is how teams triple-cart.
Wrong element. Fire. Not Dragon, not Thunder. Fire. The DPS check doesn’t care about your preferences.
Early Dragonator. Long cooldown. Save it for the airborne phase or the DPS check.
Standing in tar. The slow effect stacks. Walk through two pools and you’re stationary. Clean your positioning.
