Thus far there are 14 bosses in total, and that number will only continue to climb as time production continues. By the end of it all, I hope to have around 25~ bosses in the game. There might be more, or there could be less. Still, with the plethora of people I've still got to squeeze in there, I think I'll more or less get up to the 25~ mark with minimal difficulty.
Also, I have to note: Status effects actually WORK in this game. Unlike the last three, where they were practically useless, they have their uses in this fourth installment. Some bosses are weak to Death, Stop, berserk, Silence, etc. Slow, blind, poison, and stun are the common weaknesses, though.
I`ve also put up a few new screenshots. If you take a good look at them, then you`d be able to notice some familiar names (people from RMN). And...that`s right! There`s going to be more. They`re all going to be optional, mind you, but they`ll still be there.
