So, I was looking at the wiki page on MF mechanics https://nevergrind.com/wiki/index.php?title=Magic_Find_Mechanics, and it says that one way to increase the chance of getting uniques/sets from a boss https://nevergrind.com/wiki/index.php?title=Bosses is chaining them; however unless I'm missing something you cannot - at the moment - chain a boss. I mean, you can chain mobs after the boss is pulled, but that doesn't help for the boss' drops (horde bonus doesn't work on bosses, and that ought to stay like that imho).
So could this be implemented? Would you like to be able to pull a boss in a chain - when you've killed all the mobs prior to him/her? I know I would...

If this is already possible, please forgive me and explain me how, 'cause I'm clueless atm

Oh, yeah. That's definitely wrong. It should say +0%. I guess what it means is that you would receive that amount if it was even possible to chain them, but it's not. I'll change it to 0. Even if I coded it so you could chain them, I would change it to 0%. It would be OP!

^ tbh, I'd just like to be able to pull bosses at the end of a chain, regardless of the MF increase...
