The skeleton bone is one of sixteen bludgeon types used in rumbling. On subscription oceans, this bludgeon may only be used by subscribers. However, unlike most bludgeons it cannot be purchased at shipyards. The skeleton bone is only available in the seven colors that skellies come in. The strike pattern also contains a very large amount of small groups, with many of these groups being at least two balls in size. This makes it hard to clear through unless you can sprinkle very fast. On the flip side, the very large number of small groups allows turbo-strikers to basically strike non-stop.
