Rey Dau Spawns During Inclemency

At first, there is no way to spawn Rey Dau on command. Track his spawn time by going to your map and checking the Forecast on the Environment Overview.

Scroll down on the forecast screen until you see Rey Dau then scroll to the right until you reach the aligned color bar on Rey Dau. This should show you the remaining time left until Rey Dau reappears.

Once you beat Rey Dau after tracking its spawn time, you can post a quest through Alma to fight Rey Dau anytime.

How to Beat Rey Dau

Rey Dau Monster Fight Tips
Use Flash Pods Use Focus Strike When Its Horns Overheat Stack on Elemental Resistance Stay on its Legs Use the Environmental Traps Look Out for Its Lightning Beams Be Extra Careful in Rey Dau's Resting Spot

Use Flash Pods

Flash pods can bring Rey Dau down while he is flying or interrupt his attacks. 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.

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.

Stack on Elemental Resistance

The majority of Rey Dau's attacks are infused with lightning. Without proper resistance, any of his attacks can deplete your health fast. We recommend equipping the Hope Armor set for Divine Blessing and Thunder Resistance and eating vegetables to increase Elemental Resistance.

Stay on its Legs

The majority of Rey Dau's attacks are directed to its front and back. You can avoid the majority of Rey Dau's attacks by attacking Rey Dau's legs for an attempt to topple the monster.

Use the Environmental Traps

Use the Vine Traps to create a damage opening against Rey Dau. These Vine Traps are often found in Area 7 of the Windward Plains, an area that Rey Dau relocates to during hunts.

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.

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.

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 committing to your combos as these follow-up attacks can hit hard.
