In regards to the Cuff of the Son (Savage), we're aware that players have been having difficulties, and I think one of the contributing factors to this is that the Arm of the Son (Savage) appears less difficult. The Cuff of the Son (Savage) is an area where you need to defeat four bosses in a row, although we consider this a single boss with four different forms and each is separated into phases. However, because each boss has unique mechanics and heavy damage output, there are a lot of instances where players need to redo the entire fight due to a single mistake.
While there are exceptions, what the development team had in mind was that players would complete the Fist of the Son (Savage) and the Cuff of the Son (Savage), obtain the items for those areas, and then challenge the Arm of the Son (Savage) after. That being said, I’ve been in discussion with the development team about adjusting the damage output in the Cuff of the Son (Savage). The major concern here is that the difficulty of the Cuff of the Son (Savage) and the Arm of the Son (Savage) would be reversed. These adjustments to the Cuff of the Son (Savage) have not been finalized just yet, so please stay tuned for follow-up information.
