Try "liberating" it will circle you down to the fire and works will with the blessing.
or rearrange the line before to and a blessing falls use Falls as the connection.
Release is not a bad option either.
try using http://rhymezone.com you can use it as a rhyming dictionary but it will also link that word into One Look to find almost limitless synonyms...just start clicking until you find one that really works well for your intended use.
You did a great job giving the elements a mystical feel of something more than ordinary or even extraodinary.
I also love the enjambment lines that force you into the next stanza. It's one of my favorite techniques. But I IMHO the word Liberty, while describing the blessing does not flow into Fire as well. Maybe a slight rewording here would help that.
