I am the leader of the Katsumi Doll Masters Clan which has been going for over a year now. I decided to re post my tips here so i can give some help to those who wish to master the Boss den.

Ok This Strategy is Simple and easy and it depends on your ability to persevere

Have you ever noticed that a doll will come from the other side of the Arena just to hit u? lol

Its not doing that because it likes u lol

Have your crew go to the corners of the arena and when the next wave comes, you will see dolls come your way. Dolls have a hit list.
And the only person on their hit list is you.
So if you die they stop attacking and go Neutral(except for the Kokeshi Collectable yellow doll)

the yellow Dolls Attack on Sight, but they cannot see far so when they are neutral, stay in the corners.


When in the corners and dolls come your way,. do not unleash a rr4 fire rain or heavy water balloon or any ring of that manner in the middle of the arena.

Wait for them to come to you then destroy them useing any ring u desire. But Remember Fluffs have about a 60% percent chance of appearing after a death of a doll. yellow is 100% so watch yourself, if you have scardy cat then you are in luck. Scare the fluffy suicide %#&$&#* away and destroy it. but remember your Crew/Clan. They are here as well and if you have sand then stop it in the middle so no one gets hurt when it explodes.

Also if no dolls come after you(this does happen) then go help your crew/clan member that is the weakest or has the most dolls after them. this way you still have each others back.

this is a plan that does work, you dont have to be a team to do this, just ask your crew to please separate to the corners.

This is just my opinion and do not take it serious, but if you like it then we can give it a go. if you dislike it then post your opinion.
Thank you
