I finished that greatclub:
It's very small for a greatclub. ;) I intentionally made it the absolute smallest I could while still technically qualifying as a greatclub (48" long, 18" of 4" diameter padding plus 6" of 1/2"-thick courtesy padding), so that it would be lighter, faster, and easier to wield, especially since there's a decent chance my son might be using it from time to time.
I've named it "The Horn of Joshua" because it has the shield-crushing special ability. The walls will come tumbling down.
