                         Statues and Spellbooks
                        ========================

When you chop up a statue, with for example a pick-axe or a wand of
striking, you might find a spellbook in it. The probability of finding
one increases with increasing depth in the dungeon, and are as
follows:

Dungeon level  Probability
~~~~~~~~~~~~~  ~~~~~~~~~~~
 1, 2 and 3              0
    4 and 5           1/12
    6 and 7           2/13
    8 and 9           3/14
  10 and 11           4/15
  12 and 13           5/16
        ...            ...
  20 and 21           9/20
        ...            ...
  30 and 31          14/25
        ...            ...
  40 and 41          19/30
        ...            ...
  50 and 51          24/35
        ...            ...
  60 and 61          29/40

Please note that whether or not a statue contains a spellbook is being
determined when the statue is first created, so don't bother dragging
your statues deeper into the dungeon, just to increase your chance of
finding a spellbook in it: it won't work. A statue found at level three
will not contain a spellbook if chopped to pieces on level 40.
