And that's why I'm specifically saying that the weight isn't what I'm arguing against; if you somehow have the strength to accelerate that much mass quickly and the borderline supernatural ability to remain in place while doing so, despite basically flinging around something that's likely heavier than yourself, by all means go for it. That much mass with speed as high as seen in the games would definitely crush a person, though it does so because of weight [I]and[/I] speed (force equals mass times acceleration; high mass at low acceleration is still low force). And sure, I imagine that if you hit a cleric beast on a joint with the Kirkhammer it'd probably put that limb out of commission for a little while, but what if you didn't hit a joint? What if you don't hit a limb at all, but the torso? Then the argument of large enemies falls apart. A human-sized opponent would probably still get crushed by the sheer force of the hammer, but a cleric beast - something with mass of its own to receive that force - would probably only bruise slightly.
The Kirkhammer can be ridiculously heavy, that's fine, but the shape could be better. Yes, hit a cleric beast joint with the Kirkhammer and you'd probably have it bending the wrong way (presuming you're hitting at the right angle), but what if the hammer had narrowed on one end? Same mass, same force, but applied to a smaller area (pressure is force over area; large force over a large area results in smaller pressure). With that, you could probably break the limb regardless of where you hit, and do serious internal damage by hitting the torso. If the Kirkhammer had been cone-shaped or even rounded, it would just be a much more effective weapon.

How are the rest of you doing? Is anyone working on posts at the moment?
