This walkthrough explains in full detail how to defeat Rey Dau, from attack patterns and vulnerable spots to best weapons and methods for coming out on top.
Rey Dau in Monster Hunter Wilds
Rey Dau is a Flying Wyvern and the Apex Predator of the Windward Plains, though you’ll first encounter it in Low Rank. It wields Thunder elemental attacks and can channel this power through its tail, horns, and wings.
- Horns: Rey Dau has retractable horns on its face, which it uses to focus and direct its lightning strikes at hunters.
- Tail: Its tail is lined with spikes that can channel Thunder energy, making tail attacks even more dangerous.
- Wings: The edges of its wings also conduct Thunder energy, adding extra bite to its wing slashes.
Rey Dau often fights from the air, similar to Rathalos, staying airborne for long stretches and swooping down occasionally to unleash its powerful Lightning discharge attack. Be ready to dodge both its aerial assaults and grounded thunder strikes!
Rey Dau Location in Monster Hunter Wilds
Rey Dau is the top predator of the Windward Plains in Monster Hunter Wilds. You’ll probably catch your first glimpse of them during your fight with the Alpha Doshaguma, but your real introduction — and first hunt — happens in the Chapter Two main story quest, “The Eye of the Storm.”
When you’re tracking Rey Dau during this quest, just follow the scoutflies as they guide you to its location. After your first battle, Rey Dau won’t always be around, so you’ll have to wait for them to reappear in the Windward Plains if you want another shot at hunting them. You’ll know they’re back when a notification pops up on the right side of your screen saying, “Rey Dau has entered the locale.” Once you see that, act fast — they don’t stick around for long!
Rey Dau Weakness in Monster Hunter Wilds
Rey Dau’s weakest points are its head, wings, and tail, giving you plenty of targets to focus on during the fight. While you can attack its chest and legs, aiming for the weaker spots will help you bring it down much faster.
Both the head and wings are breakable, and damaging these parts not only hurts Rey Dau but also limits some of its more dangerous attacks. The tail can be severed too, so don’t hesitate to go for that when you get the chance.
Keep an eye out for its powerful lightning-based move, known as the discharge attack. After using this, Rey Dau’s head becomes especially vulnerable for a short time. If you’re quick, you can use Focus Mode to lock onto this weak spot and deal some serious damage!
Rey Dau Attacks in Monster Hunter Wilds
General Combat Tips
- Rey Dau knows its weak spots: It uses its head, wings, and tail aggressively, making it hard for you to get close.
- Fast and relentless: While its attacks leave it open for counterstrikes, the monster’s speed makes those openings brief.
Head Attacks
- Thunder railgun attack: When Rey Dau covers its face with its horns, get ready — it’s about to shoot a bolt of lightning, either on the ground or mid-air.
- Ground scratch + explosion: Sometimes, it scratches the ground first, electrifying the spot. It then “shoots” the mark, causing an explosion.
- Charged beam attack: If you see Rey Dau charging its head, brace for a massive thunder strike.
- Opening for a counter: After any of these head-based attacks, its head becomes exposed for a short time. If you see a red glow in Focus Mode, move in quickly for a wound attack before it recovers.
Wing Attacks
- Grounded wing slash: Rey Dau plunges a wing into the ground, then carves forward before swinging it up. You have a brief window to dodge.
- Double wing attack: A variation where it repeats the same wing move with its other wing for a double hit.
- Aerial wing dive: If it takes flight and locks eyes with you for a second, it’s about to dive and slam a wing down. Move fast!
- Flying carve attack: Sometimes, it carves the ground with a wing while flying for a few feet, leaving behind a thunder trail.
Tail Attacks
- Tail slam: If you’re near its rear, it’ll lift its tail and slam it into the ground. Dodging this gives you a good chance to attack and sever the tail, reducing its range.
- Tail swings: It can swing its tail left and right in quick succession or do a big swipe while repositioning mid-air.
Status Effects & Extras
- Weak Roar: Rare, but can be countered with Earplugs.
- Thunderblight: Makes you easier to stun. Evade repeatedly to shake it off, or use a nulberry.
- Resistance: Equipping armor with Thunder or Blight resistance helps lessen the damage and status effects.
Rey Dau Strategy to Beat in Monster Hunter Wilds
When taking on Rey Dau, some weapons work better than others. The best choices are:
- Great Sword and Hammer: Perfect for landing heavy, high-damage hits and staggering Rey Dau.
- Switch Axe, Charge Blade, and Dual Blades: Great for combining elemental damage or status effects to wear down the monster and break its defenses.
- Bow and Long Sword: Their speed and elemental power make them solid options. The Long Sword stands out in particular since its counters are a great way to respond to Rey Dau’s aggressive attacks.
Choosing the right weapon not only helps deal more damage but also gives you better control over the flow of the fight.
Gearing Up for the Battle
- Elemental weapons: Rey Dau is weak to Water and Ice. If you have a weapon with either element, you’ll have an edge Uth Duna is a solid choice for Water damage.
- Armor: At this point in the story, you likely won’t have strong thunder-resistant armor yet. Focus on gear with the least thunder penalty aim for something like -6 resistance rather than -9.
Before the Fight
- Healing items: Bring both regular and Mega Potions. If you’re low on Mega Potions, gather honey from the biome before heading into battle.
- Food buffs: Eat before the fight! Use the portable BBQ to grill a meal. Boost your health and stamina — and add Wild Herb or similar ingredients to increase your elemental resistance against Rey Dau’s lightning attacks.
Extra Tips for Later Fights
- Ammo and tools: For follow-up battles, bring Puddle Pods or Frost Pods. If you or a teammate use ranged weapons, Water or Freeze Ammo will also help chip away at Rey Dau’s health.
- Upgrading armor: Even if you haven’t unlocked stronger gear yet, upgrade your current armor as much as possible. Boosting defense can make a big difference when facing Rey Dau’s powerful attacks.
Phase 1
- Attack patterns: Rey Dau uses basic moves like tail slams, swipes, and stomps. It rarely uses its focused thunder attack at this stage.
- Your strategy: Focus on dealing as much damage as possible especially to its head and wings.
- Pro tip: Try to create wounds on its head, then follow up with a Focus Strike for heavy damage. Breaking its horns early will make the next phases a bit easier.
Phase 2
- Trigger: Rey Dau enters its enraged state, ramping up its aggression.
- New attacks: Expect a three-hit focused lightning strike. If you broke its horns in Phase 1, it’ll rely on this attack less often.
- Your strategy: Play defensively. If you’re using a Gunlance, this is the perfect time to use Wide Shells to target its wings.
- Movement: Rey Dau becomes more airborne and changes locations more often. Use the Seikret to track it easily.
Final Phase
- Trigger: Rey Dau calms down briefly but quickly shifts back into a constant enraged state.
- Your strategy:
- At first, treat it like Phase 1 but with more frequent lightning and wing attacks.
- Once you’ve dealt enough damage, it will retreat to its nest. Use this break to heal, restock potions, and sharpen your weapon.
- When Rey Dau is sleeping, start with a charged attack on its head or tail — the first hit on a sleeping monster deals double damage.
- After it wakes up, it will remain enraged until you either break its horns or defeat it.
- Endgame strategy:
- Focus on dealing enough damage to exhaust it.
- Once it’s worn out, use a Pitfall Trap or Shock Trap to immobilize and capture it.
- Alternatively, use Focus Mode to create wounds and target those weak spots for extra damage.
