Roblox Lego Ninjago Guide How to Easily Defeat the Great Devourer and Get the Vermillion Egg

Week 4 of the LEGO event introduces one of the biggest encounters yet, bringing players face-to-face with the fearsome Great Devourer. Alongside this challenging boss fight, players can earn Vermillion Eggs, unlock exclusive accessories, collect Arcane Energy, and even hatch the brand-new Great Devourer dragon.

Although the battle may seem intimidating at first, understanding each phase makes the fight much more manageable. This guide explains where to find the Great Devourer, how each battle phase works, the best strategies for defeating the boss, and everything you can earn after victory.

Where to Find the Great Devourer

The Great Devourer is located in the Shinrin world during Week 4 of the LEGO event. If you open the mini-map, you’ll notice a special icon labeled “Great Devourer.” The encounter takes place inside the previously locked mysterious door hidden within the corrupted purple area.

Like other event bosses, your rewards depend on the amount of damage you contribute during the battle. Players who deal more damage receive better loot, making solo runs especially rewarding if you can survive the entire encounter.

Great Devourer Boss Fight Overview

The Great Devourer is an enormous serpent capable of burrowing underground and launching powerful attacks from unexpected angles. The encounter is divided into three unique phases, each introducing new mechanics that require different strategies. Fortunately, once you understand the attack patterns, the fight becomes much easier than it initially appears.

Phase 1 Strategy

The opening phase is the simplest part of the encounter. During this stage, the Great Devourer mainly relies on bite attacks while occasionally diving underground before resurfacing nearby. To avoid taking unnecessary damage:

• Stay behind the boss whenever possible.
• Watch the frill around its head, as it expands just before a bite attack.
• Avoid the green poisonous clouds scattered around the arena.
• Move away from the red warning circle whenever the boss burrows underground.

The poison clouds deal relatively minor damage, so your main priority should be avoiding direct bites and underground ambushes. Keeping consistent movement while attacking from behind makes this phase end quickly.

Phase 2 Strategy

The second phase is widely considered the hardest section of the fight because the Great Devourer gains several new attacks. New mechanics include:

• Poison spit projectiles.
• Poison walls across the battlefield.
• Continued bite attacks.
• Underground attacks.

Although the poisonous terrain can limit your movement, the most dangerous attack is actually the poison spit. Using your dash ability at the right moment allows you to dodge the projectiles consistently.

Whenever possible:

• Circle behind the boss.
• Save your dash for poison spit attacks.
• Avoid getting trapped between poison walls.
• Continue attacking from the rear instead of standing in front of the boss.

Mastering these movements makes the second phase much less difficult than it first appears.

Phase 3 Strategy

The final stage introduces an entirely different mechanic focused on survival rather than constant attacking. Throughout this phase, the boss repeatedly burrows underground before triggering a devastating earthquake. Blue safe zones appear around the arena, and players must reach them before the attack lands. Follow these steps:

• Immediately move into every blue square that appears.
• Stay inside until the earthquake finishes.
• After several safe zones appear, the boss becomes vulnerable.
• Deal as much damage as possible before it repeats the mechanic.

If you fail to defeat the Great Devourer during the damage window, the safe zone sequence starts again. Thankfully, this phase is relatively straightforward once you know where to stand.

Great Devourer Battle Tips

A few simple habits can dramatically improve your success rate:

• Always stay behind the boss.
• Watch for the head frill before bite attacks.
• Dodge underground ambush markers immediately.
• Use dash primarily against poison spit.
• Don’t panic about poison clouds unless they’re blocking your movement.
• Enter every blue safety zone during the final phase.
• Maximize damage during vulnerability windows.

Overall, the encounter is much easier than many players expect after learning its mechanics.

Great Devourer Rewards

Defeating the boss rewards players based on their overall damage contribution. The loot pool includes several valuable event items. Possible rewards include:

• Vermillion Eggs
• Arcane Energy
• Exclusive dragon accessories
• Achievement progress
• Event cosmetics

Repeated victories can also unlock additional accessory sets themed around the LEGO Ninjago dragons.

Exclusive Dragon Accessories

One of the most exciting reward categories is the collection of cosmetic dragon equipment inspired by Ninjago dragons. Possible accessory drops include:

• Four unique dragon helmets
• Body accessories
• Tail accessories

These cosmetics allow players to customize their dragons with themed appearances while adding more variety to their collection.

Vermillion Eggs Explained

Vermillion Eggs are one of the headline rewards from the Great Devourer encounter. Unlike previous elemental eggs, these feature a distinctive design and contain several dragons from both current and previous LEGO events. Possible hatch results include:

• Great Devourer
• Dragon of Motion
• Ryu
• Returning LEGO event dragons

Each dragon can appear with different elemental combinations and cosmetic traits, making repeated farming worthwhile for collectors.

Great Devourer Dragon Abilities

The Great Devourer dragon isn’t just visually impressive—it also features one of the most unique movement abilities introduced during the event. Its special alternate bite ability lets the dragon:

• Dive underground.
• Travel beneath the surface.
• Reappear whenever the bite ability is activated again.

Underground movement is significantly faster than normal flight, giving the dragon excellent mobility during exploration and combat. Players can also toggle this alternate attack on or off depending on their preference.

Source Dragons Return

Players may also encounter returning Source Dragons during the LEGO event. Veterans who collected them previously can summon them using their special tools. New players, however, automatically receive the corresponding summon tool after hatching a Source Dragon for the first time.

The available Source Dragons include:

• Source Dragon of Motion
• Source Dragon of Energy

This system makes it much easier for first-time participants to unlock these special companions.

Growing and Upgrading Source Dragons

Freshly hatched Source Dragons begin as babies and require time before they become rideable. Players can speed up this process using Growth Potions available from the Blacksmith Event Shop.

Each Growth Potion:

• Costs 500 Arcane Energy.
• Reduces growth time by 30 minutes.

Using multiple potions allows dragons to reach Elite status much faster, letting players ride them without waiting through the full incubation period.

Mutation Potions

Source Dragons require a different upgrade path than ordinary dragons. Regular Mutation Potions have no effect on them. Instead, players must purchase their dedicated mutation potions from the Blacksmith Event Shop to unlock their fully mutated appearances and abilities. Planning your Arcane Energy spending carefully is recommended since both Growth Potions and Mutation Potions compete for the same currency.

Blacksmith Event Shop Changes

Week 4 also refreshes the Blacksmith Event Shop with several valuable additions. Highlights include:

• Reduced prices for Ninja Dragon gems.
• Source Dragon Mutation Potions.
• Ryu Mutation Potions.
• Growth Potions.
• Additional upgrade materials.

These discounts make it much easier to strengthen returning LEGO dragons while preparing newly hatched companions for future battles.

Is the Great Devourer Worth Farming?

Absolutely. The Great Devourer is one of the most rewarding boss fights introduced during the LEGO event. Even though the battle includes multiple mechanics, every phase becomes predictable after a few attempts. Between the generous Arcane Energy rewards, exclusive accessories, Vermillion Eggs, and the chance to hatch the Great Devourer dragon itself, this encounter offers excellent value for both collectors and progression-focused players. If you’re looking to maximize your LEGO event rewards, defeating the Great Devourer should be one of your top priorities throughout Week 4.
