                     Experience value of monsters
                    ==============================

                by Roger Christman (dvl@psuvm.psu.edu).


Monster XP isn't in any of the other spoilers, probably because it
cannot be found in the source files directly. Instead, it's a function
that is called when a monster dies. Similarly, "monster difficulty",
which determines when a monster may appear and how valuable it is for
sacrifices is also not easily available. This depends on whether or not
your system admininistrator deleted the monst.c file. A few days ago I
actually created a list of this data. All the XP values are there.

Lev = hit dice of monster. This influences how likely it is to hit you,
      and figures directly into the XP calculation. If a monster comes
      "early" (if its standard level is a bit higher than the dungeon
      level), it may lose a hit die. If it comes "late", it may gain a
      hit die. XP is adjusted accordingly.

Diff= relative difficulty of the monster. This is used to evaluate the
      the corpse when it is sacrificed and also to determine whether a
      monster will be summoned, aside from special cases: water
      demons, mushrooms calling purple worms, etc.

      The maximum difficulty of new monster is the average of dungeon
      level and player level -- this is easily observed in play.

XP  = Earned XP for killing a monster with this many hit dice. Again,
      having more or fewer hit dice will modify this value. In
      particular, growing brown molds before slaying gets you XP.
      Conversely, Stormbringer and polymorphing into Vampire Lords will
      tend to Reduce the XP you get from a monster.

An ad hoc formula that seems to work:

   XP >=  Lev * (Lev + 6) + 1       (more for special features, etc.)

Example:     Lev   0    1    2    3    4    5    6    7    8
             XP    1    8   13   28   41   56   73   92  113

This was worked out experimentally. Higher level monsters, however nearly
always have good AC, or deliver heavy damage, or have a special attack,
or something, so other factors get added in.

Well, here is the list, sorted by difficulty (i.e. order of appearance).

Caveat: I've only gotten past the Castle once, and in that game my pet

have experience.
