Event duration (JST): 2019 Dec 18 ~ 31
You can obtain Fragments of Etre x35~40 from the quest. Even if you have no plan to use Etre, it's better to have enough fragments to limit break.
This quest can only be played once a day.
You can gain rare items like Phantom Spheres and Awoken Souls by completing record missions.
Achieve missions of EX quest 1 & 2 to get 2x Fragments of Will of Rainbow.
Cat Claws isn't that good. Dragonhron Lance will be useful once Dragon-type enemy raid event is added to the game.
Anyway, just collect enough recipes and scrolls.
Bloody Bone is weak to Striking-type attack and Earth elemental attack. Use Mont Leonis's Body Slam or Etre's ability to deal over 2000 damage.
Malboro & Bewitching Witch vision cards will be helpful.
You can complete the mission by dealing 1,000 damage to 2 enemies (or 700 damage to 3 enemies) at once.
Use AoE abilities like Mediena's Cosmo Plume, Gilgamesh's Kotetsu, and Mont's Destiny Cross (Limit Burst) to deal damage to multiple enemies simultaneously.
Summons like Golem and Behemoth work fine as well.
