This is one of those bosses who play alongside the illusion of fear. The bosses' whole gimmick is to keep you stressed during the entire fight, impeding your ability to dodge attacks reliably. I've lost to him a ton of times because I took a hit and lost my concentration, but the moment I started ignoring hits, I started doing really well. Once you let the boss dictate the pace of the battle, you've already lost. This applies to a ton of other bosses as well, such as all the godhome-exclusive bosses, Hive Knight, Failed Champion, Soul Tyrant, etc. these bosses get a ton of damage off exploiting you being in a disadvantageous state; they can rush you down or teleport to you when you try to escape, or lob projectiles from a distance to force you to move.

Simply put, if you take a hit, just accept it happened and forget about it. Once you start worrying about your health, you start worrying about healing, and that often ends in taking more hits, and then death. The best advice I can give is to never drop the offense.
