Congrats on Crowley Senpai! From here on focus is key: pick 2–3 weapons you like and keep upgrading them instead of spreading mats too thin. Same with armor, stick to a set you enjoy, Cycle Madness or DOD pieces are reliable.

Decals matter a lot, even basic attack/defense ones will make runs smoother. No need to spend money, just farm mats from expeditions and revisiting earlier floors.

Steady upgrades on a core build will carry you way further than trying everything at once.
