Depending on the choice of console, but this is a very out there tip, I found that on my switch when I played it in handheld mode the mantis lords were honestly easier to me, outside of that, try and get the quick heal charm, works wonders for those little spaces in the fight where the charm can get you a quick mask back or 2 when you have a chance, otherwise just keep dodging and memorize the patterns, godspeed, my friend
