It would be amazing if there was a config option to make it so waystone travel would cost and consume some item (say, emeralds) instead of experience. It would be ideal if the item could also be configurable so that a modpack could specify its currency item.

I've seen others ask for this on the curseforge comments pages as well, so I know there is demand for it. This would be very useful for economy-based servers/modpacks as there is not a clean way to convert currency to experience that doesn't cause other issues gameplay-wise due to how experience works in the game.

I thought about just making the scrolls/stones cost currency to craft, but the novelty of having to walk to a hub/location that contains a waystone before teleporting is too important to me to give up. No other mod really has teleport structures in that generate sporadically in the world, so there really is no alternative to do this through editing crafting recipes of other mods or items.

I think likewise, it would be great to use emeralds/diamonds instead of experience, because the only reason I don't have much desire to use these obelisks is the difficulty of getting experience. Otherwise I'd use them almost all the time...

This is a great idea to keep waystone travel even more rare/costly, which can be great for some servers.

This is now possible in the new warpRequirements option using e.g. add_item_cost(waystones:warp_dust, 1)

Using items is great, is it possible to also allow the use of currency from a currency mod such as Lightman's currency ?
