Shining blade

Exploration Stage: Miracle Fair
From: Oliver Winter
Description: According to Icy, in order to capture the spirits who serve Krampus, they need a tool to draw runes on the ice. He says it is not a carving knife or a chisel used by carpenters, but a magic skate blade. Could you please help me find it together?
Completed: You've found your magic skates! They sparkle and shine as if all the lights of a carnival had come together in one spot. I can't believe I have the magic item in my hands. I hope this item has enough power to bring my daughter and son back...
