Yeah I figured the items would be quite confusing without an index to explain what each does, honestly I'm still in the process of figuring out how I want an item index to function and look. I tried my best to draw them in a way that made sense at least except for the single orange grade item. Really all that does is create an "explosion" where you kill an enemy that damages anything nearby. As you stack it, the explosion would do more damage hence the rarity of its drop rate. Everything else is pretty basic, movement speed, more coin drops, magnetize coins, skill charge rate increase, and increase health.
