"From the look of it... That must be this region's apex predator." A Flying Wyvern that rules the Windward Plains as its apex predator. It has adapted to the lightning that accompanies the Sandtide, with most sightings having occurred during the storm. Its ability to discharge electricity in powerful attacks pose a threat to even the most experienced hunters. Rey Dau is a Flying Wyvern first introduced in MHWilds.
Monster Characteristics:
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.
Helpful Hints:
When a Rey Dau's wing or tail touches the
ground while charged, it causes a reaction
that produces a mantle of fulgurite. Not
only does this widen the appendage's attack
range, but it also increases the monster's
charging capacity—so make a point of
breaking these parts. Their heads may also
be vulnerable after a discharge attack.
Hunters are advised to bring thunder-
resistant armor and water-based weaponry.
Additional Information:

amplify, and discharge the Sandtide's lightning.
