[spoiler]Should have paid attention lmao[/spoiler] By jumping on the Stands back and holding on to bite its neck, she basically stabbed her arms on it's shoulder spikes. Leone shouted in pain as blood ran down his neck, but it wasn't as fatal due to the Stand's armor like plating on itself. The Stand jumped and fell on it's back, crushing Frost and sending the spikes all the way through her arms.
