Sloppy magic versus calculated magic.
Neither is fundamentally better than the other, each has it’s strengths and weaknesses. Sloppy magic may be include the risk of going wrong, but usually utilizes intense emotion which is the one of most powerful things in magic. Calculated magic can lack raw power but makes up for it in being very precise and effective.
Sloppy magic is for the rushed sigil you draw on your math test that you’re sure you failed, but with your intense desperate magic, surprisingly find out later you passed with an ok mark. Sloppy magic is for emotionally, violently cursing your abusive ex to suffer endless insomnia and horrific regret. Sloppy magic isn’t ‘half assed’ magic, or ‘amateur magic’, it’s very simply neither calculated nor precise. Instead of elaborate rituals, it’s rage, desperation, elation, despair, raw love, pure joy, etc. It’s emotional magic, rushed or spontaneous magic, unprepared magic, but still just as powerful a magic calculated.
Calculated magic is making your bigoted boss lose his job by targeting his superiors, making them notice his shortcomings that they’d previously been blind to. Calculated magic is the elaborate, long thought out wards that you permanently have surrounding your home, with intricate sigils and laboured over energy grids. It’s calm, well researched, complicated magic plays the long game. It’s demands less immediate results, and more long thought out processes of magic, unravelling things thread by thread or tearing them down brick by brick, ensuring success.
Calculated magic sacrifices time for exact, effective results, whereas sloppy sacrifices precision for raw intense power. Calculated magic tears down the wall carefully but laboriously brick by brick with your bare hands, sloppy magic slams a pickaxe into the wall and immediately knocks it down without care about where the bricks fall, whether they’ll land on your feet.
Always be aware of your actions, your words, your intention, your emotions.
