The yedae's roar is massive, sounding more like a deep, resonate, guttural growl that echoes the empty places of the frozen world. It consists of two parts; the first is a wave of sound that blasts all targets near the creature. Any creature within a 100-foot radius of the yedae suffers 11 (2d10) thunder damage. In addition, each creature in this radius must make a Wisdom save (DC 17) or be stunned until the end of their next turn. The sound wave precedes the frozen blast of its icy breath. In the same round that the sound strikes anyone within range, a 20-foot cone of icy breath emits from the yedae's mouth. All creatures within this cone must make a Constitution save (DC 17), taking 42 (12d6) cold damage on a failed save, or half as much on a successful one.
