Did you know that you can change Miriam’s look beyond changing the color of her outfit in Bloodstained: Ritual of the Night? Once you have either the invert ability or the high jump, you can obtain it. While not the best armor in the game, it does have solid defense and a good amount of luck, plus it gives Miriam a more conservative outfit and removes the crystals from her skin.
If you want this outfit for yourself, return to where you fought the boss in the Towers of the Twin Dragons. If you look up to the walkway directly above where you first met them, you’ll notice a hole. Simply high jump or invert and you’ll come straight to the chest containing the Valkyrie armor, which changes Miriam’s appearance.
It’s important to note that Todd can’t change the color of this outfit, so what you see is what you get. There’s also no way to change her outfit to this without wearing it, so you’ll have to decide between aesthetics and functionality.
