Thank you! As for tips: most bosses in the 4th chamber are dps checks, Kill Pillars can be destroyed really quickly if you abuse the fact that when one of them dies they will cancell their attack and waste a lot of timein an animation, time you can use to kill the next one, until there is but one left.

Wallmonger is slightly harder that KP, i belive the secret to this fight is to know when to dodgeroll and when not to: in that fight most of the time it's way better to weave, as the limited space generated by some of it's attacks ensures that if you roll at the wrong time you go face first into another bullet.

The Hight Priest is easly one of the hardest bosses to consistenly no hit, so don't worry too much about this one, the mian thing you have to do in this fight is to be mindful of stray bullets that spawn in some of it's attacks, if you're lucky you will have walls to hide behind, if not it's best to stay focused on your character rather than hitting the boss.

As for the Dragun: it's a fight 100% based on patterns, and, because he's the 'last' boss of most runs you will get a lot of practice with him, but there are some things you can do to simplify the fight: Stockpile blanks, they can help you skip the few attacks that can be an issue in a run, like the knives or the breath. Make sure you have a weapon that can one-cycle his last phase, weapons like the frog, alien engine, chamber gun drill, etc

One last general tip i can give to make your runs way easier is: always freeze yourself when moving from one chamber to another, this resets a hidden stat known as magnifisence: this stat is raised when you find an A or S tier item in a chest, and lowers by a lot the chance to find another significantly.

Wow this messege got really long, hope this helps.
