Hearthstone’s newest expansion, The Witchwood, added several new legendaries to the game. One such legendary, a Shaman card called Shudderwock, has been plaguing players for the past two weeks. But Jesse Hill, a Hearthstone community manager, took to the forums to announce that Shudderwock would be getting a quality of life change in an upcoming patch.

“In a future update, we will be doubling the animation speed of Shudderwock’s Battlecry so it will lessen the impact on the overall pacing of your current Hearthstone match,” Hill said. “In addition, the amount of Battlecries Shudderwock can reproduce will be capped at 20.”
