A Universal Dungeon for Time Travel? I'm a Demon Warlock

When the beast tide comes, others are guarding the city and squatting on the city walls, shooting arrows and scraping, I turn into a demon and go on a rampage; others are struggling to gain levels by farming monsters, but I kill a demon to permanently add all attributes. The witch partner's aerial support is beautiful and elegant, the mobs will break if touched, and the high-level monsters will have to lie down when they come.
