some short insight since i run this type of character as well.
1. It is best to guardianize for a build like these since the additional stats for being level 150 really help out.
2. Try out multiple Sol Neko armors so you could fit in as much compression as possible.
3. Try to get the new misc from the Snugglefest event, it is currently one of the best miscs for BMs because of the stat boosts and a burn potence for your neko burns.
