0.23.0

• A battle on levelling, as the original does, from level 25 - where
  challenges stop being declined. In simulation it lifts battles from 21 to
  30 a week each and the realm's pace from 0.900 to 0.917, and narrows the
  gap between alignments (4.9% to 3.1%). At the level-60 wall, where
  level-ups are rare, it changes almost nothing.
• The eight named uniques, each in its own slot behind its own level,
  worth far more than the curve can roll: the Lantern of Small Mercies, the
  Kumquat of Ages, the Seven-League Courser, the Last Honest Ledger, the
  Bell That Must Not Ring, the Moon-Rake, the Crown of Minor Kings and the
  Door That Was a Mimic. A climb from 1 to 80 turns up about one. The
  Courser is a mount: it carries a whole quest party, two ranks of Stride
  faster. Nameless uniques are gone - they out-numbered the eight and made
  their worth meaningless. Ones already found keep their value.
• Rivals and trophies. Whoever beats you most is named in WHOAMI, on
  the /whoami card and on your page; beating someone ten or more levels
  above you leaves a trophy to keep.
• Not shipped: the original's ±10% good-and-evil battle modifier. Good
  gains too much: the gap between alignments doubles (3.1% to 7.7%), with
  chaotic good +4.7% and neutral evil -3.0% beyond luck. At ±5% it is still
  +3.4% for lawful good and a 5.7% spread. The switch (MORAL_BATTLE)
  stays at 1.0 for everyone.
