i wld suggest using either kanon or ivris, not both at same time. since both of them do anti-debuff roles (thus overlap). use kanon if you do not need healing (aka easier content) for his def buff, use ivris if u need the heal she offers. another thing to note is copra also offers def buff (at 7 stars that is to be released in time to come, it is equivalent to Kanon's). thus, you should probably use zergel for his atk buff in place of kanon.
