The slot machine already gives random components, to make the chest more "special" and so for example we can stack them to use them when needed I suggest that when you use it in your inventory you can select the component you want from the rarity of the chest (so he didn't feel like rerolling the slot machine but not only for components)
#Make that the chest from the slot machine give the item of your choice from that said rarity
delicate cape
tall yoke
I think i'd be better if a chest just had multiple items, that way it has a purpose but also doesnt make it super easy to get what you need
