How to Beat Rey Dau

Rey Dau Monster Fight Tips
Use Flash and Frostburst Pods Use Focus Strike When Its Horns Overheat Look Out for Its Lightning Beams Be Extra Careful in Rey Dau's Resting Spot Take Advantage of Environmental Traps Stack on Elemental Resistance

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
Windward Plains

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
Windward Plains

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
Windward Plains

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
Windward Plains

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.
