In my pack, waystones can only be found, can't be crafted or moved. There is anyway to share the waystones with other players / team members?

You can use a Bound Scroll on a waystone and share the bound scroll with another player.

Wait, are waystones automatically shared with other players / team members? My friend can already see all the waystone I've activated

No, only global waystones are shared.

Nvm, she activated it before. Thanks

Bound Scroll

Wait, a bound scroll lets you teleport to the waystone, I don't want that, I just want them to be able to see the waystone
