Monster Hunter Wilds Rey Dau Boss Fight Guide

Known Habitats: Windward Plains Breakable Parts: Horns, Wings, Tail Recommended Elemental Attacks: Ice and Water Effective Status Effects: Poison (2x), Sleep (2x), Paralysis (1x), Blastblight (2x), Stun (1x), Exhaust (2x) Effective Items: Pitfall Trap, Flash Pod, Dung Pod
Rey Dau, the first dragon you'll face in Monster Hunter Wilds, possesses the lightning element, rendering it immune to lightning-based attacks. However, it's highly vulnerable to water and ice. Prioritize attacking its head (4-star weakness) or wings (3-star weakness). Avoid its sturdy torso and well-protected legs. Utilize all status effects except Stun and Paralysis.
Use a Flash Pod
Employ Flash Pods to temporarily stun Rey Dau, creating openings for critical hits. During its lightning attacks, aim for its glowing red horns (enter Focus Mode for better visibility) for maximum damage.
Wear Element-Resistant Gear
For increased survivability, equip gear that enhances elemental resistance. The Hope Armor set, with its Divine Blessing skill, reduces damage and offers protection against lightning and fire. Consider consuming a meal that boosts elemental resistance as well. If dodging proves difficult, stay close to Rey Dau's legs; it primarily attacks the front and rear areas.
Pay Attention to the Environment
Rey Dau will fly between locations. In the open plains, utilize Vine Traps on the lone tree to briefly stun it. Exercise caution near its nest, as it employs a powerful follow-up lightning attack in that area.
How to Capture Rey Dau in Monster Hunter Wilds

Capturing Rey Dau offers alternative rewards. Reduce its health until it's near death (indicated by a skull icon on the minimap). Lay a Pitfall Trap (Shock Traps are ineffective against lightning dragons) and quickly use a Tranquilizer before it escapes.
Monster Hunter Wilds is available now on PlayStation, Xbox, and PC.
