You gotta keep a firm grip on the spell, not just the heat. Use a containment charm—think of it like a tiny, invisible cage that holds the flame until you’re ready to let it out. And remember, never let your emotions flare up while you’re working with fire, or the sparks will just get bigger. Practice with a wand that’s a bit lighter, so you’re not overexerting yourself. If you keep your focus and keep the wand steady, the blaze won’t get out of hand.
