C4 is the easiest for this example. I can definitely manage explosives. You can rather easily make things which blow up.

Let’s make this easier then, I go to the woods and set up a huge fucking boulder on an elaborate pulley system (don’t worry about me finding them, I live in Finland were boulders and rocky surfaces are a plenty. My cousins actually operate a gravel business, so they have lots of proper gear for breaking rocks into smaller rocks, and vehicles to do those things with. So let’s say there’s a pit. I lay a ton of harsh gravel on the bottom of it, a proper few meter layer. Then I take a loader full of massive boulders. And another. And a third one. Place them around the pit. Place myself in the pit, and remotely activate the loaders to drop all those boulders on me. Oh and I didn’t mention, but I put a bed in the pit with me. It’s a bed of extremely sharp knives, covered by a thin cardboard so I don’t get stabbed if I easy myself onto it. On top of that, there’ another bed, upside down, also loaded with insanely sharp swords. All of the boulders will fall into the pit, crushing the bed system, which stabs and slices me into pieces while the boulders to the rest of the work. (The bed frames are soft enough so that they can hold knives, but will be utterly deformed by the boulders so they won’t stay in the way.

Then I’ve also paid for a crazy cousin to empty both barrels of a shotgun to my face with a full metal slug right as the stones start dropping.

But… I’ll survive?

So a magical but injured life is possible, but a magical but non-injured one isn’t?

Cool. Cruel, but cool.
