While this is a minor bug, it pains me greatly.  Whenever I use Cluster Bomb on my Thief with the Dreamer shortbow, it doesn’t always rain unicorns.  On low height/arc detonations, it will rain 3 unicorns in place of the bombs.  Tis a great sight that makes me all warm and tingly on the inside.  However, on high arc detonations, the unicorns vanish, and I just get unsightly bombs instead.
