Diablo in Hogwarts

His soul traveled through the magical world and became a noble young master of Hogwarts. He has long silver-gray hair and dark gold pupils. He looks gentle but is actually sinister. Awakening the "Diablo 2 Dungeon System", only he can enter secret realms such as Tristram to farm monsters and upgrade equipment. There is a dungeon challenge once a week, which will drop rune words, alchemy formulas, and skill fragments, all relying on self-study to synthesize magical skills. The wand can be equipped with "Ace's Whisper", and the potion can be equipped with "Siphon of Life". A top student with a physique that can dominate the classroom, and a defensive character that does not allow his friends to be bullied. Anyone who touches his brother will immediately have the means behind it. Exploring the forbidden forest, competing in the academy, and quietly becoming stronger. The dark wizard is stirring and the ancient seal is loosening. He has modern thinking and alien systems in his hands, stirring up the storm in the magic world. In this life, he does not rely on blood, but only on strength.
