If you want one of the strongest Monsties available in the early game, Dreadqueen Rathian is the one to chase. This powerful Flying Wyvern mutation is accessible before you even leave Azuria, and building her up to S-Rank gives you a serious advantage heading into the tougher content ahead. Here is every step you need to follow to unlock and farm her as early as possible.
What Is Dreadqueen Rathian?
Dreadqueen Rathian is a 7-Star mutation of the Rathian line, described in-game as a Rathian Deviant whose tail venom has evolved into a deadly purple miasma cloud capable of suffocating prey. She is a Speed-type Fire attacker and one of the strongest Monsties you can obtain during the Azuria arc of the game.

Step-by-Step Guide to Unlocking Dreadqueen Rathian
Step 1 โ Get Your First Rathian Through the Story
You cannot farm Rathian eggs until the story sends you to the right location. Progress through the Endangered Species story quest in Azuria, specifically the quest known as “A Step Toward Conservation”, which unlocks shortly after meeting Eleanor, the sister of the Queen of Vermeil.
During this quest, you will encounter an Invasive Yian Garuga guarding an Endangered Species Den. You cannot defeat it outright during this part of the story. Instead, your goal is to repel the Yian Garuga and drive it away from the den. If you are struggling, bring a blunt weapon or a Long Sword and focus on breaking the Yian Garuga’s legs, which restricts its moveset and causes it to retreat.
After repelling the Yian Garuga, enter the den to collect your first Rathian egg. The story will then guide you to release this Rathian via the Habitat Restoration system, which sets up everything that follows.
Step 2 โ Unlock the Sunpetal Plains Camp
Before Habitat Restoration becomes available in a specific area, you need to establish a camp there by defeating the Feral Monster that controls the zone. For Sunpetal Plains, defeat the Feral Yian Kut-Ku marked on the map with a red icon. Once the camp is established, you can begin releasing Monsties into that habitat.
Step 3 โ Farm Rathian Eggs from the Sunpetal Plains Dens
Return to the Sunpetal Plains and begin farming Monster Dens for Rathian eggs. The most consistent farming spot is the small valley near where the original Rathian egg quartz was located, near the sleeping Yian Garuga. Additionally, the area north of Azuria Castle near the lookout tower past the Ranger Camp has two Golden Dens and a Blue Den that regularly yield Rathian eggs.
A few tips to maximise your egg farming efficiency:
- Nighttime farming tends to yield higher rarity eggs more consistently than daytime, though this is not guaranteed
- Pull every egg from every den in the area rather than searching only for shiny or gold eggs
- If no dens are present or the eggs are poor quality, save at the nearest Catavan then reload your save to reset den spawns
- If you encounter a Rathian in the wild, throw Paintballs at her to guarantee she retreats to her den, which will contain a Potent Rathian egg and significantly speeds up farming
- You can also repel a Rathian in combat for the same guaranteed Potent egg result
Aim to collect enough Rathian eggs to begin releasing consistently. Roughly 8 to 12 levelled releases are needed to push the Ecosystem Rank to S quickly when using the same-species multiplier.
Step 4 โ Release Rathians via Habitat Restoration (NOT the Stable)
This is the most important step and the one that trips up many players. You must release your Rathians through the Habitat Restoration menu at the camp, not through the Stable. Releasing via the Stable does not count toward the Ecosystem Rank and will not unlock the mutations.
Additionally, the habitat you release into needs to contain three or more poisonous monsters to unlock the Dreadqueen Rathian mutation specifically. The Sunpetal Plains habitat already satisfies this condition naturally, so no extra preparation is needed if you are releasing there from the beginning.
Step 5 โ Raise the Rathian Ecosystem Rank to S
Continue farming Rathian eggs, hatching them, and releasing them via Habitat Restoration until you reach the required Ecosystem Ranks:
| Ecosystem Rank | Mutation Unlocked |
| Rank B | Rathian becomes more common and eggs improve |
| Rank A | Pink Rathian mutation unlocks |
| Rank S | Dreadqueen Rathian mutation unlocks (requires 3+ poisonous monsters) |
To speed up rank progression, release higher-level Monsties rather than freshly hatched ones, as levelled Monsties contribute significantly more to the Ecosystem Rank per release. Releasing Monsties of the same species or element also activates a multiplier that accelerates rank gains further.
Step 6 โ Farm Dreadqueen Rathian Eggs
Once the Dreadqueen Rathian mutation is unlocked, her eggs will begin appearing randomly in the dens of the Sunpetal Plains habitat. Continue pulling all eggs from every available nest in the area. Dreadqueen Rathian eggs are lime-green with purple tiger stripes, making them visually distinct from standard Rathian eggs once you know what to look for. The egg is also confirmed by name when it appears in the den, so you will know exactly when you have found one. Her eggs can appear in both Golden Dens and regular dens.
Step 7 โ Push Dreadqueen Rathian to S-Rank
After hatching your first Dreadqueen Rathian, continue the same process of farming, hatching, and releasing Dreadqueen Rathians into the habitat until her Ecosystem Rank also reaches S. At S-Rank, her eggs will spawn more frequently and hatch with S-Rank Genes more consistently, which are the strongest gene options available and the foundation of any top-tier Monstie build.
Dreadqueen Rathian Skills
| Skill | Type | When Unlocked | Effect |
| Dual Razor (Kinship Skill) | Active | Level 1 | Deals Fire damage to all enemies, then grants Attack Up to the user |
| Flame Tempest | Active | Level 20 | Deals Fire damage to all enemies with a chance to inflict Burn |
| Venom Queen | Active | Level 60 | Deals Non-Elemental damage to one enemy with a chance to inflict Severe Poison |
Additionally, Dreadqueen Rathian can hatch with the following skills from her skill pool:
- Kinship Skill+ (S): Slightly increases Kinship Skill damage
- Instigator (S): Makes enemies slightly more likely to target the user
- Toxic Sweep: Deals Non-Elemental damage to all enemies with a chance to inflict Poison
Can You Get a Dual-Element Dreadqueen Rathian?
Yes, it is possible to obtain a Dual-Element Dreadqueen Rathian by introducing Rathians into a different area habitat with a different element type and raising the Ecosystem Rank there as well. However, unlocking those additional habitats requires defeating the relevant Feral Monsters in other regions, making this a mid-to-late game goal rather than something to pursue in Azuria.
Key Mistakes to Avoid
- Never release Rathians via the Stable. Only releases through the Habitat Restoration camp menu count toward the Ecosystem Rank
- Do not search only for shiny or gold eggs. Pull every egg from every den to maximise your chances
- Make sure your habitat has three or more poisonous monsters before attempting to unlock Dreadqueen. The Sunpetal Plains satisfies this automatically
- Keep at least one Dreadqueen Rathian in your party or use Eco Conservation in the Habitat menu to prevent her from being removed accidentally when you add new Monsties to a full habitat
The Dreadqueen Rathian is one of the best investments you can make in Monster Hunter Stories 3: Twisted Reflection during the early game. Follow this guide consistently and you will have an S-Rank Dreadqueen in your party before ever leaving Azuria, giving you a powerful advantage for everything the game throws at you next.
