These quests are unlocked after progressing toManiac Difficulty.

If you plan on farming this quest, you’ll want to eitherfind a group of other playersto do it with orset up your own party. One of the best characters for farming bosses like this isEugendue to his high single-target damage throughSumrakand his ability to paralyze the enemy usingParalyzing Bullet.

For the rest of your party,bring characters that can also inflict Paralyze, Freeze, or Slow, like Io, Lancelot, or Narmaya.
The key is toParalyze the Griffin right as it enters Overdrive, which allows you to quickly Break it and continue to deal damage before it uses its whirlwind attack. Once you’ve got the timing down, you may quickly clear this quest for tons of Fortitude Crystals.
