Question with buying higher items

. How does one purchase an item like rite of passage or any of these high priced items that are more than an inventory full of divines (600 I believe?). Do you contact the seller and do equivalent currency like fractures orbs or is there a way to purchase higher from their shop ? Thanks guys!

you don't need to carry all these orbs in you inventory, they will be removed from your stash automatically when you buy the item.
