Rey Dau can also appear in the Wounded Hollow. When hunting for Gold Crowns, that locale is a good place to scout and reroll for monster sizes.

How to Beat Rey Dau
| Rey Dau Monster Fight Tips |
|---|
|
|
Use Flash and Frostburst Pods
Flash Pods can interrupt Rey Dau’s attacks or bring it down during flight. Rey Dau will fall and will be toppled if you flash it while flying, making a damage opening for your team to hit his weak spots. Keep an eye out for Rime Beetles as well to acquire Frostburst Pods – ammo that Rey Dau is elementally weak against.
Remember that Rey Dau will develop a certain resistance to flash pods when used frequently. This resistance is a recurring mechanic across all monsters.
Use Focus Strike When Its Horns Overheat
Use Focus Strike when Rey Dau's horns overheat after a lightning beam attack. After a successful Focus Strike, Rey Dau will be toppled and is open for a damage phase.
When in Focus Mode, Rey Dau's horns will glow red similar to wounds when it overheats. This indicates that the horns are currently a weakness you can exploit through Focus Strikes.
Look Out for Its Lightning Beams
Rey Dau can release a Lightning Discharge from its horns, this attack can either be quickfire beams that deal low damage, or it can be a supercharged beam that can cart you in one shot if you do not have enough elemental resistance.
Watch out for Rey Dau's horns as the telegraph for his beam attacks are its horns pointing forward. Once you see this telegraph, start running away in a diagonal direction to avoid the beam, or ready a shield to take it head on.
Be Extra Careful in Rey Dau's Resting Spot
Fighting Rey Dau in his resting spot (Area 17) can be surprising as his attacks now have follow-up lightning explosions. Be careful in committing to your combos since these follow-up attacks can hit hard and possibly cause Thunderblight.
Take Advantage of Environmental Traps
Rey Dau will fly and move to different parts of the map, so it's a good idea to look out for environmental traps that you can use against it to speed up the hunt.
Falling Boulders, Windward Plains
 |
|
| Locale | Area |
|---|---|
 
|
|
There are several Falling Boulders in Area 1 and 7 of Windward Plains that you can use during your hunt. Rey Dau rarely ventures in Area 1, but you can lure it with Luring Pods to this area.
Position Rey Dau carefully underneath the boulders and use your Slinger to pull down the boulder and knock it off its feet!
Vine Traps, Windward Plains
 |
|
| Locale | Area |
|---|---|
 
|
|
There are overgrown trees in Area 7 and Area 8 of Windward Plains where you can pull down the vines to set a Vine Trap. Lure Rey Dau towards the trap so you can get a few hits!
Keep in mind that the trap won't hold Rey Dau for long, so stay close to it as it approaches the trap!
Sharp Crystal Pillar, Windward Plains
 |
|
| Locale | Area |
|---|---|
|
|
|
A Rey Dau hunt can can start in or move to Area 5 of Windward Plains where there are 3 Sharp Crystal Pillars that you can bring down to knock it off its feet.
This area is very small so you'll need to be careful positioning Rey Dau as its chain attacks can cover the entire area.
Falling Grounding Pillar, Windward Plains
 |
|
| Locale | Area |
|---|---|
|
|
|
Near the end of the hunt Rey Dau flies to Area 17 of Windward Plains to rest. This area has a large Grounding Pillar that you can bring down on Rey Dau to do massive damage.
Positioning Rey Dau beneath the pillar though is a bit tricky as the area is very large. We recommend putting a Pitfall Trap below the Grounding Pillar and luring Rey Dau onto the trap first, then bringing down the pillar when it's stunned!
Stack on Elemental Resistance
The majority of Rey Dau's attacks are infused with Thunder Element. It is best to have high Thunder Resistance when needed, since having no proper resistance will have its elemental attacks deplete your health fast.
When fighting Rey Dau for the first time, we recommend equipping the Ingot Armor set for Divine Blessing and Thunder Resistance as well as eating vegetables to increase Elemental Resistance.
Rey Dau Attack Patterns
Moveset and Openings
| Attack | Description |
|---|---|
| Supercharged Lightning Beam | Extra appendages appear on Rey Dau's neck and bright bolts of lightning gather on its spine, then it fires one devastating lightning beam. Dodge this attack by running to the side, then prepare your Focus Strike for Rey Dau’s horns. |
| Flip Slam | Rey Dau performs a backflip and then quickly slams its wing on the ground. Take advantage of this attack as it gives brief damage window after the flip. |
| Lightning Beam | Rey Dau plants his wings on the ground or takes to the air and fires one lightning beam. Run towards Rey Dau in a diagonal direction to avoid getting hit. In High Rank, Rey Dau can do this move twice consecutively, with a varying delay on the second beam. |
| Quickfire Beam | Rey Dau plants his wings on the ground and fires lightning beams in quick succession. Continuously roll in Ray Dau's direction in a diagonal pattern to dodge the beams. |
| Flying Wing Drag | From a flying state, Rey Dau drags his wing toward a target. Dodge away from the direction of the wing drag or use a Flash Pod to topple Rey Dau. |
| Heavy Tail Slam | Rey Dau raises its tail high and slams it on the ground. Roll to the side or run towards Rey Dau's legs before the tail hits you. |
| Double Tail Slam | Rey Dau winds his tail either to the left or right, then slams it in both directions. Depending how near you are, roll towards Rey Dau's legs or away from the tail to avoid this attack. |
| Wing Slam | Rey Dau raises either one of his wings and then slams it on the ground. Roll backward or forward once you see it raise its wing. |
| Grounded Wing Drag | Rey Dau burrows its wing on the ground and then drags it forward. Roll towards Rey Dau's legs if you're near enough, or dodge away if you're farther off from the monster. |
| Horn Thrust | Rey Dau points his horns forward and thrusts toward a target. Roll sideways to avoid the hitbox from the front and back. |
Alternatively, all of Rey Dau's attacks can be guarded with a Shield.
