Winter Wyvern

Winter Wyvern soars upon an arctic wind, granting her unobstructed movement and allowing her to exhale a blistering chill into each attack. While soaring, her attacks travel further and faster, and slow enemies with a magical freeze that strips them of 4 / 6 / 8 / 10% of their current health each second.

Grants Winter Wyvern the item Eldwurm's Edda, which can be consumed to increase the current and maximum level of a basic ability by one and Winter Wyvern's base intelligence by 25% of its current value at the time of consumption.

Winter Wyvern dispells then freezes an enemy in place while striking those nearby with a maddening curse which causes them to attack their frozen ally with increased attack speed. The frozen ally and those cursed to attack their ally are immune to all damage from their enemies with the exception of damage from Winter Wyvern or her controlled units. Enemy heroes which enter the cursed area after the cast add to the duration of the curse.
