PIERCES SPELL IMMUNITY:No
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 [6.0, 7.0, 8.0, 9.0]% of their current health each second. Her sight is also hardened against night's chill, granting her 400 additional vision range at night while soaring.
Upgradable by Aghanim's Scepter.
Enemy units can only receive the Arctic Burn debuff once per cast.
This ability does not affect Roshan.
Reduces Winter Wyvern's attack point to 0.1.
