That is unfortunately not known at this time; I would guess that at least 20 or so for a Legendary, perhaps 30-40 for Epic and Dragonforged. Silver Coins are needed to max Shadowforged, so after level 99, you don't need FB anymore.

Keep in mind there are new FB rarities for Rings/Amulets and there is rumored to be another tier coming into the game in the near future, so the amount needed may change depending on the rarity of FB you're using.
