Material Component: When a wish duplicates a spell with a material component that costs more than 10,000 gp, you must provide that component.
XP Cost: The minimum XP cost for casting wish is 5,000 XP. When a wish duplicates a spell that has an XP cost, you must pay 5,000 XP or that cost, whichever is more. When a wish creates or improves a magic item, you must pay twice the normal XP cost for crafting or improving the item, plus an additional 5,000 XP.
