Items and Meals to Prepare
Ammo Crafting Material | |
---|---|
![]() | - Crafting Material for Ice Ammo └ Not enough in your starting items, so a must - Register in Radial Manu for crafting |
Immobilization | |
![]() | - Almost essential to suppress movement - Also register in Radial Manu for crafting - Too many uses will make it ineffective |
![]() | - Required as crafting material for Flash Ammo - Bring the maximum amount |
Capture Item | |
![]() | - Pitfall Trap is the only valid option for capturing Rey Dau └ Get used to the lag before activating the Pitfall Trap |
![]() | - Essential for capturing └ Tranq Bomb is also acceptable |
Damage-Boosting Items | |
![]() | - Can significantly shorten the time by using it for attack boost |
![]() | - Attack Up Item with a 3-minute effect time - It overlaps with Demondrug, so use them together - Easy to gather through Material Gathering Requests |
![]() | - Attack Up with a 30-minute effect time - If you have extra, use Mega Demondrug |
![]() | - Attack Up Item with a 3-minute effect time - Overlaps with seeds and drugs, boosting damage further - An option if you want to minimize time loss |
![]() | - Boosts attack just by having it in your inventory - Reward from the side mission “As Gatekeeper” |
Use Attack Up Items Before the Hunt
Demondrug has a long effect time, and the preparation time before use is a bit longer, so it's best to use it at the Base Camp beforehand. Might Seed and Demon Powder should be used just before descending from Seikret to avoid wasting them.
Prepare a Pitfall Trap for Capturing
Rey Dau cannot be captured with a Shock Trap, so be aware that it can only be captured with a Pitfall Trap. Depending on the starting position, the travel time can be very long, so once you see the "weakened" status, stop its movement with Flash Pods and set the Pitfall Trap immediately.
Meat + Egg is Recommended
Ration | Additional Ingredients | Finishing Touches |
---|---|---|

For meals, choose Attack Up Meat + Fluffy Egg (Airy Egg). The Finishing Touches can be anything, but Eastern Honey is recommended as it significantly increases recovery.
Strategy and Tips for Temp Rey Dau
Battle Strategy Guide
Aim for the Hard Parts of the Head and Wings
Rey Dau has a vulnerability to Ice Element damage on its head, allowing for efficient damage dealing. It is recommended to position yourself in a way that targets the head, extending through the central body, and then to the wings for optimal damage output.
Remember the Attacks That Should Be Guarded
How to Do |
---|
+ (Press together when an attack is coming) |
After shooting or reloading, automatic Guard doesn't activate, so make sure you can perform manual Guard quickly. Roar offers a chance to attack, and the discharge attack can be countered with Focus Strike. Mastering this can help shorten the hunting time.
Recommended Guard: Wing Sweep (Left-Right)
At close range, Guard is recommended for the wing sweep attack. After the sweeping attack, it may transition into a discharge attack, so use the brief opening after the second sweep to throw a Flash Pod and create distance.
Recommended Guard: Discharge Attacks
The discharge attacks from Rey Dau, such as the railgun, require Guard, so make sure to block them properly. Once you're used to it, it becomes an opportunity to attack the exposed weak spot.
Flash Pod Flying Attacks To Stun
▲Flying attacks are aimed at you, so deploying a Flash Pod at your feet will cause it to crash.
Rey Dau often uses flying attacks, and you can bring it down by hitting it with a Flash Pod during its flying phase. If you close the distance, you'll face more attacks like wing sweeps or head thrusts that can be blocked with Guard, so always aim to bring it down by Flash Pod during flying actions to maintain a safe distance.
Limit Flash Pod to 5 Uses
Flash Pods are effective against Rey Dau for about 6 uses, after which they no longer interrupt its movements. During Capturing, the monster becomes harder to stop, and will often move around. So, try to limit the use of Flash Pods to 5 times as much as possible.
Make Sure to Knock Down If the Horn's Weak Spot Is Exposed
After discharge attacks or large moves, when the horn’s weak spot is exposed, be sure to use a Focus Strike to down the monster. Especially after blocking a large move with Guard, the exposed weak spot will be right in front of you, making it easy to land a Special Attack to down the monster.
Craft Ammo and Flash Pods Before Running Out
Always craft Freeze Ammo and Flash Pods before they run out. If you wait until they're depleted to craft, you’ll need to switch ammo or reset your Flash Pods, which takes extra time.
Destroy Tempered Wounds At the Right Time
Tempered Wounds can be destroyed when timed right, excluding effects like Paralysis or Traps. It’s an opportunity to pile on damage, so avoid destroying them all at once.
Capture Before Moving If Possible
▲ Only Pitfall Traps work, so use Flash Pods to make sure the capture is successful.
If the monster moves after it weakens, it will take extra time, so when the Palico says 'It's weakening,' it's best to immediately capture. Use Flash Pods to stop its movements, set a trap, and safely capture the monster.
How to Unlock and Spawn Temp Rey Dau

Best Farming Spot for Tempered Rey Dau
Area 7 is Recommended

Area | Details |
---|---|
Area 7 | - Use "Falling Boulder" to deal huge damage and knock down - Close to Base Camp |
The recommended area for farming Tempered Rey Dau in Windward Plains is Area 7. Using the environment, "Falling Boulder" allows you to deal significant damage while knocking down the target, making it easier to handle safely. It's close to the starting position in Area 8, making it easy to lead the monster there, and it's also conveniently near the Base Camp.
Windward Plains Map GuideArea 5 Has Multiple Falling Boulders

Area | Details |
---|---|
Area 5 | - Three environmental hazards similar to Falling Boulder that can deal high damage and knock down - Pop-Up Camp "Area 4: West" is nearby |
Area 5 has three environmental hazards, "Sharp Crystal Pillar," which have the same effect as Falling Boulder, allowing for a significant increase in farming speed. If Tempered Rey Dau is not in Area 5, you'll need to lure it with ammo or other methods and then turn it into a quest.
▲The pillar in Area 5 can be activated with a Heavy Bowgun, making it convenient than using a Slinger.
