Luca walked down to the dungeons from his common room and through them, shivering slightly. The darkness was welcome to Luca, and he could feel the bloodlust. He bit his lip and swallowed, focusing on keeping himself calm instead of flipping out and killing the next person who came through. He would never want to hurt anyone, and knew he would be judged harshly throughout his life for what he was anyway. If he harmed someone, he basically was screwed. Luca shut his eyes and rubbed his temples, before opening them once more and walking into his classroom.
He sat down and looked at the instructions on the board, eager to start so that he could distract himself from his predatory thoughts. He stood up after Educator De Cendres had finished talking (snapping) at them, and walked over to the ingredients cupboard. After a few trips, he had everything he needed and he sat down at his table, organising everything before he pulled his mortar towards him. He moved his pestle out the way and placed the bezoar in the mortar, crushing it into a fine powder with his pestle.
He added 4 measures to the potion. He then added two measures of the standard ingredient and heated it at medium temperature. After he'd counted five seconds, he turned the heat off and peered at his potion. He waved his wand over the potion and leant back, looking to see how long he'd have to wait. He looked at his cauldron, but it was only a pewter cauldron so he'd have to wait for 40 minutes. He leant over and picked up his book and began to read. His leg twitched continuously. After 40 minutes, he dropped his book back into his bag. He continued on with the rest of the instrunctions until he finished by stirring two times anti-clockwise, and then he waved his wand over his potion.
