Getting up from her seat, Ellura picked up her parchment containing the list and followed the example set by other students to the supply cabinet. She gathered as much as she could carefully before returning to her workstation, repeating the process a second time to get the very last ingredients.

Remembering the first step given, Ellura poured in the milk, filling her cauldron halfway. However she had missed the professor's action of cleaning the cauldron, herself unfamiliar with brewing potions in the first place.
