Nature sense has been fixed. Look at its AB file (and also Elementalism
sense) to see how it has been updated to relate to the new Runes
skill...

Fuse has been added to Runes. Though you need the meld skill in your
primary guild skill specialization before you can access it. Enjoy!

Penned by my hand on the 7th of Urlachmar, in the year 106 CE.
