Cormac and Katie turned their weapons onto the final vamp-feri and it blazed into a fiery final death before shooting towards the Lich. She whipped up a shield that all of the pellets hit and ruptured before they could even touch her. Through the fire and the smoke, I saw Trixymort cackling madly as her shield was impenetrable. I scrambled back up to my feet, the hood of the invisibility cloak almost slipping as I stood by Snape. Dolohov hid behind her while Severus and I sprayed molten lava out of the tips of our own wands, hoping against all hope that this would be enough to burn through her shields.
