Rey Dau Large Monsters
Description
The flying wyvern that reigns supreme over the Windward Plains’ ecosystem. It is able to store, amplify, and discharge the Sandtide’s lightning.
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.

Crown Sizes
Most monsters can spawn in different sizes. Some special sizes are marked with crowns in the Monster Field Guide. Crown Monsters don’t have different stats or drop rates, but earning crowns is tied to some Achievements/Trophies, so completionists will want to pay attention to the info below. In-game, use your binoculars to look for a crown icon over a monster’s name.

Large Silver Crown Size: 2365.64 (115%)
