                <Description>
            Modification of emerald for decay blocks. Adjusts until we get something that works.
            Idea is single block deposits, fairly rare.

                    <Comment> At any time, there are 15*15 = 225 chunks ticking. Or more.
                              We want some white decay at all times, but at 12 minutes to surface,
                              not so much that we can't do anything at all </Comment>
