In Monster Hunter Wilds, players often seek tougher battles beyond the usual hunts, and the Arch-Tempered Rey Dau answers that call with a significant increase in difficulty. This revamped electric wyvern introduces new, powerful attacks that can quickly overwhelm unprepared hunters. However, with the right preparation and tactics, it becomes a rewarding opponent to conquer and farm for rare materials.
When and How to Hunt Arch-Tempered Rey Dau
Arch-Tempered monsters appear exclusively during limited-time events, and Rey Dau’s enhanced form is no exception. It is accessible through the Event Quest named A Silent Flash and the Free Challenge Quest The Shining Storm Rages. These quests have appeared in specific windows, such as late April to mid-May, but are not always available. Hunters should watch for their return to take on this electrifying foe.
Exploiting the Wyvern’s Weaknesses
Despite its increased toughness, Arch-Tempered Rey Dau shares many vulnerabilities with its standard versions. Hunters should focus on:
- Elemental Weakness: Ice-based attacks are most effective.
- Weapon Types: Cutting and blunt weapons deal better damage.
- Targetable Parts: The head, tail (which can be severed), and both wings can be broken.
- Status Effects: Blastblight, Exhaust, Poison, and Sleep work well; Paralysis and Stun are less reliable.
- Useful Tools: Flash Pods and Pitfall Traps can turn the tide of battle.
Strategies to Overcome Arch-Tempered Rey Dau
Preparation for this fight demands weapons imbued with ice elements and armor that offers strong resistance to thunder damage. The Arch-Tempered variant boasts significantly higher health and durability, so swift, calculated strikes are crucial.
This wyvern is notably more aggressive, chaining attacks that can catch hunters off guard, especially when trying to recover from a hit. Utilizing your Seikret companion to revive quickly after being knocked down is essential to maintaining momentum. Healing safely away from the monster’s reach is always a better option than risking another hit.

A unique challenge in this fight is the frequent lightning strikes triggered by many of Rey Dau’s moves. These strikes increase stun chances and disrupt counterattacks, forcing hunters to remain cautious. While offset attacks can still be effective, other counters often get interrupted, leaving hunters vulnerable. Equipping the Evade Extender skill can greatly improve dodging capabilities against these electric hazards.
If the lightning strikes become overwhelming, destroying the blue Fulgurite crystals on the wings and tail temporarily disables the effect for about three minutes. Although this reduces damage potential by diverting focus from the head, it’s a useful tactic when struggling with constant follow-up attacks.
New Attack Patterns to Watch For
Arch-Tempered Rey Dau introduces a dangerous new move that involves shooting lightning directly beneath itself, a departure from previous safe zones under the monster. Getting caught in this attack can lead to a devastating charged beam capable of causing a knockout. Hunters should dodge immediately upon noticing the charging animation to avoid being caught off guard.
Breaking wounds on this wyvern remains a valuable strategy for knockdowns, but Arch-Tempered Rey Dau’s increased wound resistance makes it tougher to exploit. Opportunities for significant damage appear mainly after its strongest charged beam attack. Mounting the monster, using traps like pitfall and vine traps, and deploying Flash Pods when it takes flight are key to controlling the fight.
Surviving the Electrified Onslaught
The battle largely revolves around endurance and survival, as the wyvern remains enraged throughout the encounter. Prioritizing health management is critical to avoid instant defeats. After a few cartings, capturing the monster becomes a practical option to conclude the hunt efficiently.
Rewards Exclusive to Arch-Tempered Rey Dau
Defeating this enhanced wyvern yields rewards similar to its Tempered counterpart but with notable additions. Instead of the usual Hunter Symbol III, hunters receive the Rey Dau Certificate Y, a vital material for crafting the new Rey Dau Gamma armor sets for both hunter and Palico. This material also enables upgrades to Defense Charm V and Power Charm III talismans. Since the Arch-Tempered Rey Dau is only available during specific events, the exact rewards may vary if it returns in the future.
