Originally, the Beastmaster SP2 ability was intended to be Feral Sacrifice (F.サクリファイス, F. Sakurifaisu?), which would have sacrificed the player's current pet in exchange for a Stoneskin effect absorbing HP of damage equal to the pet's former HP as well as a Reraise effect. Players unanimously loathed Feral Sacrifice and vocally protested the planned ability in the official forums. The development team eventually relented and created Unleash instead, which was far better received.
