i see, makes sense. Its been a long time since i played HK, but you can also increase charm slots.
Also you’re not supposed to be able to use all of them at once, you have to change based on situation (although you can have one charm over thr limit at the cost of double damage received)
good luck with your custom map search though, Hollow Knight is a very good game
i drank too much last night and now i feel a bit too sick. I live alone so cleanup and cooking are a bit challenging
