This mod adds two spells.
The first spell places a mark.
The second one returns you to the marked location.

There are no limits on time or range. You can place the mark, go as far as you want, and then return back at any moment. The mark won't expire, nor will it activate by itself. Only you decide when to go back.

If you found one of the spells but not the other, it is guaranteed that you will find it in the next Holy Mountain (once per run).
