So how do you get the new transmutes for the eternal stuff? Is it all through discoveries? I tried to look it up on WoWHead and WoWWiki but they don't have info on the new stuff yet.

And on that note... does anyone have the new transmutes? I'm looking to transmute some earth/life into shadow.

You seem to get them as discoveries from doing transmutes. I've been doing the titanium transmute as often as it's up ('cause I still get points from it) and discovered eternal life to eternal fire as a result.
