[[Patch 2.0.6]] controversially[http://diablo.incgamers.com/blog/comments/diablo-3-patch-2-0-6-notes-legendary-materials] removed [[Legendary Materials]], which changed the crafting costs for every level 70 [[RoS]] recipe. Prior to that patch Rozpedin's Force required 1 [[White Oak SpliterSplinter]] and 1 [[Death's Breath]] to craft.
