[Ellen] Arctic Hunt

Every 15s, Ellen applies a Hunting mark that lasts for 15 to a random enemy. When hitting an enemy marked with Hunting with EX Special Attack or Swift Scissors/Charged Scissor Strike from Dash Attack: Arctic Ambush, pressing Basic Attack or Special Attack allows Ellen to immediately trigger the skill again with no cost or other requirements. When she obtains Flash Freeze Charge, each excess point of Flash Freeze Charge increases Ellen's ATK by 12%. This effect lasts for 10s and stacks up to 9 times. The duration of each stack is calculated separately.
