In Monster Hunter Wilds, Rey Dau emerges as a commanding Flying Wyvern, reigning over the Windward Plains as its apex predator. Dubbed the “Shining Thunder Wyvern,” this creature captivates with its lightning-charged attacks, shimmering golden scales, and intense combat encounters.
Launched on February 28, 2025, for Windows, PlayStation 5, and Xbox Series X/S, Monster Hunter Wilds introduces Rey Dau as a thrilling challenge in the sixth main series installment. This article delves deeply into Rey Dau’s physical traits, behaviors, in-game roles, and combat strategies, incorporating recent developments like the Arch-Tempered event during the Festival of Accord: Blossomdance (April 22–May 6, 2025).
Rey Dau’s Physical Characteristics
Rey Dau is a massive bipedal Flying Wyvern, stretching approximately 2,571.35 cm, its form perfectly suited to dominate the Windward Plains. Its body is adorned with bony golden scales, contrasted by smaller black scales on its underbelly, joints, and wings, lending it a majestic yet fearsome look.
Unlike conventional Flying Wyverns, Rey Dau’s wings form a single membrane, akin to pterosaurs, with bladed protrusions doubling as weapons. Its compact, serpentine head boasts two rows of teeth and mandible-like structures, while its neck reveals slits that produce glowing blue, fin-like extensions when channeling electricity.
The standout feature is its large, foldable horns, which act as a rail gun for lightning attacks. Post-electricity absorption, its wing blades and back spikes glow vibrant blue with fulgurite, amplifying its combat abilities. These traits, distinct from monsters like Rathalos or Tigrex, equip Rey Dau to excel in the stormy Sandtide environment.
Rey Dau’s Behavior and Combat Abilities
Rey Dau’s fiercely territorial demeanor makes it a relentless foe, attacking any intruder in the Windward Plains, especially during the Sandtide’s thunderstorms. As the region’s top predator, it harnesses storm electricity to enhance its attacks, with fulgurite on its carapace emitting sounds that alert nearby monsters, escalating the area’s threat level. Its combat blends agile aerial strikes with devastating lightning assaults, demanding constant awareness from hunters.
- Lightning Railgun Blast: Fires powerful lightning through its horns, leaving them open to attacks after discharge.
- Fulgurite Wing Blades: Crystallizes sand into sharp fulgurite blades on its wings post-lightning, boosting slicing power.
- Electric Spear Stab: Charges horns for piercing electric melee strikes, effective in close quarters.
- Aerial Maneuvers: Executes acrobatic wing slashes, using its pterosaur-like wings for swift, offensive mobility.
Hunters can counter by evading the telegraphed railgun charge and using Nulberries for Thunderblight. Targeting the horns after a blast triggers a stagger, offering critical damage opportunities.
Where to Encounter Rey Dau in the Game
Rey Dau is exclusive to the Windward Plains, a dynamic biome in Monster Hunter Wilds marked by shifting sands and frequent thunderstorms. It’s most active during the Sandtide, where lightning supercharges its abilities.
Players encounter it in story quests and the notable event quest “A Silent Flash,” featuring the Arch-Tempered Rey Dau, available from April 29, 2025, at 9:00 AM PT, during the Festival of Accord: Blossomdance (April 22–May 6, 2025). This High Rank quest, part of the April 4, 2025, title update, yields materials for crafting the “Rey Dau γ Armor Set” and “Rey Dau γ Palico Set.”

Combat Strategies for Defeating Rey Dau
Overcoming Rey Dau demands strategic planning due to its lightning attacks and aerial agility. Ice weapons, such as the Glacial Agnesis (Great Sword) or Frostbinder (Bow), are ideal, targeting the head and horns for optimal damage. Status effects like Sleep and Blastblight can disrupt its aggression, while Pitfall and Shock Traps offer control. The Arch-Tempered version, with intensified attacks, requires precise dodging and stamina management.
- Weapon Selection: Opt for Ice-element weapons; Dual Blades or Insect Glaive shine for mobility.
- Exploit Horns: Strike horns after railgun blasts to stagger, creating damage windows.
- Manage Thunderblight: Use Nulberries to counter Thunderblight from lightning strikes.
- Trap Tactics: Deploy Pitfall Traps on the ground and Flash Pods to ground Rey Dau mid-flight.
- Arch-Tempered Prep: Wear high Thunder-resistant armor (e.g., Inagami α) and eat for Elemental Resistance.

Official In-Game Description and Lore
Monster Hunter Wilds describes Rey Dau as:
“The flying wyvern that reigns supreme over the Windward Plains’ ecosystem. It has adapted to the Sandtide – when it most frequently appears – and is able to store, amplify, and discharge the storm’s heavy lightning to lethal effect. Rey Dau is highly territorial and will attack any and all intruders on sight. The fulgurite against its carapace emits a sound that puts every monster in the region on guard.
Threat Level (危険度): ★★★★★”
This lore highlights Rey Dau’s supremacy and its synergy with the Sandtide’s storms. In the game’s narrative, it serves as a major challenge but not the flagship, with cutscenes focusing on its rivalry with Arkveld, hinting at a larger ecological struggle in the Windward Plains.
Fascinating Facts and Trivia About Rey Dau
Rey Dau’s design and lore are rich with cultural and developmental details, deepening its allure. Its name, combining “rey” (Spanish for king) and “dau” (Vietnamese for head/leader), underscores its regal dominance. Fans initially called it “Thor Magala” during a Summer Game Fest 2024 stream, likening its horns to Gore Magala, a nickname later acknowledged in a Monster Hunter YouTube demo. Though once considered the flagship, Rey Dau plays a secondary role to Arkveld in cutscenes.
Rey Dau electrifies Monster Hunter Wilds with its lightning prowess and commanding presence, making it a must-hunt for thrill-seekers. From its storm-charged attacks to the Arch-Tempered challenge, this Flying Wyvern tests every hunter’s skill. Ready to conquer the Windward Plains?
