Challenge 3 Gimmick/Tips: Explanation and Clear Guide Video (Japanese)

• The boss have 2 attack skill:
  • The first one is an AOE slam attack that apply a Healing Down debuff that decrease the healing that your ally received and also apply DEF UP buff to itself.
  • The second one is an AOE nuke attack that deal massive amount of damage.
• You should wait for the Defense UP buff on the boss to expire (roughly around 2:26) before using all your DPS skill.
  About 20s (around 2:06) later the boss will use the 1st skill and apply the DEF UP again.
  If your DPS is strong enough, just use all of their skill and you should be able to clear the stage within 80s.
• The boss 2nd attack skill deal a massive damage that can easily kill your backline.
  You should use someone like Serina or Neru (Bunny Girl) to reposition your tank forward to avoid getting your backline killed.

Challenge 5 Gimmick/Tips: Explanation and Clear Guide Video (Japanese), Clear Guide Video (No Explanation)

• The stage will have 2 enemy with the Elite Enemy marker beside their health. These 2 simply have too much HP and cannot be killed normally.
  
• The 2 Elite Enemy marker each have their own skill that give massive buff to other mob.
  You will have a difficult time killing the mobs when they get buffed, so stop their buff by using CC like Taunt or Stun on them.
• Because the Elite Enemy cannot be killed. You will need to kill the specific mob to force them to retreat to the next area.
• The Elite Enemy are part of the stage gimmick so you are not required to kill them to clear the stage. You only need to kill all mob and the boss.
• Refer to the first video for the specific target.
