u should join our discord server to discuss about it easier. its like Purification. get ur gears through Beelzbub bosses in Dream theatre Reverse. and craft stone in the machine to tier up just like puri.
Each char has its own way to make the boss die with him/her
And then we have Seha the team killer
Dont worry Seha has his coolness when killing the boss too :^)
It was fun to fight tiamat as Nata
