Rey Dau is the first true dragon you’ll encounter in Monster Hunter Wilds. As an electric-element monster, it's naturally immune to lightning attacks. However, it shows strong weaknesses to Water and Ice damage. Its head is the prime target with 4-star vulnerability, followed closely by the wings at 3 stars.

Avoid focusing too much on the torso—it's quite durable. If the head proves difficult to hit consistently, aim for the tail instead. Legs are heavily armored, so they’re not ideal targets unless you're using them for positioning.

When it comes to status effects, prioritize Poison, Sleep, or Blastblight over Stun or Paralysis, which are less effective. Since Rey Dau resists paralysis and uses lightning attacks frequently, those ailments won’t give you much of an edge.

Use a Flash Pod

Wear Element-Resistant Gear

Don’t forget to prepare with a meal that enhances elemental defense. If dodging feels tricky, position yourself near the monster’s legs—Rey Dau primarily attacks forward and backward, so staying close here can reduce incoming damage.

Pay Attention to the Environment

Stay patient, watch your surroundings, and use terrain advantages wisely to avoid being caught off guard.

How to Capture Rey Dau in Monster Hunter Wilds

Defeating Rey Dau isn't the only way to earn rewards—you can also capture it. To do this, reduce its health until the skull icon appears on your minimap. At this point, deploy a trap to immobilize the monster.

Since Rey Dau absorbs electricity, Shock Traps are ineffective. Instead, use a Pitfall Trap, then follow up with a Tranquilizer to ensure the capture succeeds. You only have a short time window, so be ready with your tools and positioned correctly.
