I've used an auto clicker to Splash to 99 magic multiple times. Highly recommend doing that to lower the risks of getting banned due to botting.
I've had a macro recorder record teleporting before where I had recorded 120 minutes of me training myself and that seemed to be working just fine too. I've used the same method for glassblowing and different other skills where you basically only have to bank your inventory. (Herblore, Crafting, Cooking, Fletching)
So I totally disagree with Powerful.
