Hello, I noticed in the WR run that during the boss fights the person flys while using the breath, is there a reason for this (is it faster)?

Late response sorry!, from what I remember I was under the impression that attacking the center hitbox does more damage I think? I think its also harder to miss shots that way.

Another tip, For rock golem we also waste a couple frames on purpose between shots so that we can manipulate his attack pattern to give us the item rocks needed to refresh the breath meter
