By default the table is sorted by: relics that are un-vaulted, then by the current sum total of all the item on the relic in platinum, and finally by ducat value.
I primarily created this in order for me to more easily determine which relic I should run when I am not looking for any prime part in particular. Usually this is not to big of an issue but I have a lot of old relics that I don't really want to run randomly... So I spent weeks creating this site.
