The recipes to craft each level of rune are only showing 3 ingredients each. The minor and major rune seem to have no trading post listing at all at the upper right side of the pages. The superior version shows a TP listing but appears to have no price, which most likely means there are none for sale.
The superior rune of the revenant is used in a recipe to craft a superior rune of the herald, and it appears this is the only way to get the herald rune.
http://wiki.guildwars2.com/wiki/Superior_Rune_of_the_Herald The superior rune of the herald is showing a TP price of over 75 gold, which means somebody is using superior runes of the revenant to craft them (unless there is another way to get the herald rune and the wiki is just missing the info).
Judging by the wiki none of these runes are bound at all and the wiki is only showing 3 ingredients for each of these runes, so I have no idea if the recipes are complete. You can give it a try and see if it works.
http://wiki.guildwars2.com/wiki/Evergreen_Lodestone used for crafting all versions of the revenant rune and it goes for over 3 gold each on the TP, which isn’t too expensive.
There’s something charming about rangers.
Pretty sure the herald runes are being extracted from non salvageable gear.
Good possibility.
However, it seems there is no way to craft rune of the revenant of any type.
I just noticed the wiki doesn’t have a source of where to get the recipe (recipe sheet or discovery). I had just tried this out myself: the Evergreen Lodestone needed for the recipe can’t be placed into the discovery window as it doesn’t show up at all in the window to add. I checked the trading post for a recipe sheet but nothing came up.
I’m guessing they haven’t released everything yet for us to craft the runes of revenant or obtain it in any other way.
