That right, I found the book, but I have no experience with the boss it's self, so I am looking for people that do to help do the battle, I suggest bringing 1, 5* elemental weapon (preferably a Polaris or the 5* shock brandish) and adequate shadow defense, also, make sure to bring at least 10 sparks of life. Thanks in advance.

Also, if you have a party and are looking for 1 member, I want to join, I want as much experience with the boss as possible before doing it.
