Event Overview:

Stack Null Gravity Barrier Monsters!

The main gimmick is Gravity Barriers so bring all NGB monsters. There are other null-able gimmicks but they are not really needed.

Alternate Bounce and Pierce Monsters

There are both obstructors in the dungeon. Pierce obstructors appear throughout the dungeon and bounce obstructors appear in the last stage. Alternate both hit types to deal with them.

Be Careful of RNG/Wide Range Bump Combos

When you clear the shields before the last stage, they will summon a colored Murasame. Although it is not the end of the world, it is better to avoid letting her summon in the first place. However, if you break the shields in the last stage, all of them will deal high damage to you as well as extra gimmicks like Ability Lock and ATK Down.

Have At Least 2 Meteor/Command SS

The first two boss stages has damaging mobs and Dark Murasame. Use a multi target SS on each stage to clear all of them. You don't have to actually hit or deal damage Muramasa with them.
