The addition to the game is part of the Patch 4. If you're a level 40 Final Fantasy XIV player and have already completed the main scenario quest, Stormblood, you'll be able to take on either Normal or Extreme versions of the Rathalos quest, known as "The Great Hunt. There's also a ton of goodies to look forward to, such as the Poogie and Palico minions, Rathalos armor set, a BBQ spit, and even a Rathalos mount that you can ride around throughout Eorzea.
I will tell you some tips to clear Rathalos Ex. Party: go with 3 tanks and 1 healer.
But 3 times your party KO, you lose. Also you can heal tanks and need to Esuna asap the debuffs.
You can use Regen on tanks or let them heal themselves if they're PLD. After that, smashing A button like mad until the times end or they finished killing Garula. Should be a tank riding it so less healing for healer.
Remember all Rathalos' movements so you can dodge him. After that, just repeat the phase, bring him down and attack until he dies.
If not enough DPS and run out of time, he will enrage. I only got the song and Poggy minion tho.
The only attack with a marker is his fireball attack where he will target a random player and deal fire damage to them. Clockwise tail swipe — he will swipe his tail behind him and move it clockwise.
Only saw the Rathalos mount once, but didnt get it. Well, it takes me nearly 20 times to try since I didnt play Monster Hunter, dont know the mechs, but thanks to my fc member Pickle's tips and Lyn Frost - who cleared it 5 times before, I cleared that Rathalos.
Remember, avoiding the hits are more important than just yolo run at him. Watch the boss' movements carefully.
Good luck, and don't smash your controller or keyboard. Need to stay calm and cool. Breathe in, breathe out.
