General Annoyances:
* Bureaucracy: Wizards are often solitary, independent thinkers who hate being bogged down in paperwork and regulations.
* Loud, Ignorant People: Wizards value knowledge and may find it frustrating to deal with people who are dismissive or disrespectful of magic.
* Disrespect for Magic: A wizard might be upset by those who fear or belittle magic, even if they don't directly attack them.
More Specific Examples:
* A Warlock might hate their patron. The deal they made could come with harsh consequences, and they may resent their dependence on a powerful entity.
* A Necromancer might hate the living. Their desire to explore the mysteries of life and death could lead to a disdain for the living who fear their work.
* A Wizard who studies nature might hate pollution or deforestation. They may find it a desecration of the natural world and a threat to the power they draw from it.
Humorous Answers:
* Running out of spell components. The frustration of a magical project being halted due to a lack of ingredients.
* Being mistaken for a magician. Wizards are serious practitioners of magic, and they don't appreciate being compared to entertainers.
* Having their magic mispronounced. Even the most powerful wizard can be sensitive about the proper pronunciation of their incantations.
Ultimately, what a wizard hates most depends on the personality, backstory, and the specific type of magic they practice. There are endless possibilities!
