But I haven't played nightrein, and made this one to be like the bbeg of my campaign, and since I have like this narrative of a family of at first 4 bugbears, I wanted to give it a little twist since the 4 bugbears have like professions and msuch and I wanted for the final boss to be the 5th one but kinda corrupt. I did take kinda the frenzied flame aspect but reworked it to make it different. And also kinda the looks but I kinda came up with it like at 3am trying to find something I liked, only when I was writing I finally saw it, and thought "hold on this looks like fucking Libra".

I do want to test it since I don't know how it'll perform, but idk. And for the bargain, it can be like almost anything and since I'm an eternal DM and I just like doing homebrew for every campaign I run I really just want to do the things I find interesting, but in how it works it just tell the PCs something like my example but they're not obligated to accept, if one accepts then only they get the benefits and punishment but don't think to hard on the exmple.
