Transcription of spells is...imperfect...so your mileage w/ a spell may vary. That is one way to handle over-powered.

• 🧙‍♂️ Modify the D&D magic system to prevent overpowered characters.
• 📚 Keep spell descriptions mysterious by allowing wizards to choose spells by name but not read the spell descriptions.
• 🎓 Create a master wizard NPC who controls the distribution of spells to limit access and make them earned through tasks and proving responsibility.
• 🏫 Introduce magical colleges with difficult admission processes, tuition fees, and alignment restrictions to obtain spells.
• 🖌️ Consider having spells tattooed on wizards' skin, requiring magically tattooed artists and making high-level spells more expensive.
• 🔍 Spells should vary in damage, range, and other factors, reflecting regional and dialectic differences in spellbooks.
• 🎲 Introduce spell checks by rolling a 20-sided die to determine success and effectiveness of spells, creating a chance for failure or misfire.
• 🔥 Critical spell failures can have unexpected consequences, such as self-inflicted damage, mutations, or catastrophic effects.
• 💡 Encourage players to think strategically and consider potential risks and consequences when casting spells.
• ⏳ Spells can be cast multiple times a day without limits, emphasizing the potential danger and unpredictability of magic.
