Pixie can be replaced after wearing it, but it can only be replaced when the Pixie is damaged, otherwise it will be detrimental to itself. When replacing the Pixie, you need to deal with the bad Pixie before you can invite a new Pixie to wear it. Once you wear a new Pixie, you need to protect it well.
You can change the brave that you wear, but you can only change it when you have to. For example, if the brave appears broken, the broken brave must be replaced, otherwise it will be detrimental to yourself.
When replacing the brave, you need to wrap the broken brave in red cloth and bury it in the ground. Or invite the broken brave to the temple and ask a master to deal with it. After the bad brave is dealt with, you can invite a new brave to wear it.
After changing into a new brave, don't replace it at will. Once you wear a brave, you need to protect it well. Unless it is the kind of brave that has not been exposed to light, it will affect yourself.
