We know roughly what the next Witcher 3 expansion is going to be about but what we do not know if what the expansion will come with. This latest leaked was said to have come from CD Projekt Red.
The details were spotted on the CD Projekt Red Forum before it was taken off but some fans manage to capture the details before that happen. The details were later posted on Reddit.
According to the Reddit post, the new expansion will dance around the Brotherhood of the Wolf and that it will come with a new sword called Bone Sword that will have some to do with the Brotherhood.
The expansion will also come with a few new Gwent cards as well as a few new combat moves. It was also revealed that the expansion will come with 2 standard endings and one secret ending.
The leak also suggests that Trophies collected throughout the game will offer better buffs now.
