Changes

Deaths Breaths are not a [[legendary material]], though they are required for many in virtually all level 60+ and [[end game]] crafting purposes, including recipes in Reaper of Souls. These include [[training Artisans]] [[Artisan]]s, [[enchanting]], upgrading [[gems]] (Royal and Flawless Royal quality), and [[crafting]].  Since they Death's Breath are [[account bound]] (BoA), drop primarily from Elites, and drop at higher rates on higher difficulties, they may function as a [[bottleneck]] on crafting and other item upgrading functions in Reaper of Souls, forcing players to spend a fair amount of time playing the game and harvesting Death's Breaths (and other materials/gems) rather than simply buying or trading for them.(The bottleneck effect is strongest for new players to Reaper of Souls. After some weeks of play time most players accumulate a surplus.)

Blizzard provided the drop rates for Deathss Deaths Breaths when complaints about their infrequency were voiced shortly after the launch of Reaper of Souls.
