ZangbandTK is Angband 4.2.6 with Zangband's character rebuilt on top of it. This
page is the honest inventory: what is in the game now, and what is not.

===============

Zangband's lethality
--------------------

Every monster carries **73% of Angband's hit points** and **50% of its armour
class**. Monsters die sooner and are easier to hit, so fights resolve in fewer
turns — in whichever direction they were going.

Those numbers are measured, not invented. Across the 450 monsters that Zangband
2.7.5 and Angband 2.8.1 have in common, Zangband's carried a median 0.73× the
hit points and 0.50× the armour class of the release it forked from. See
:doc:`balance` for the full account.

A wilderness
------------

Zangband's defining feature, and the largest piece of work in the game so far. A
world **2064 grids square**, generated from a seed and never stored, with the
town standing in it and roads leading out.

- Terrain follows from height, population and law; danger follows from law alone.
- The surface is one continuous sheet that scrolls as you walk, not a set of
  discrete levels.
- Deep water can be waded into, and drowned in.
- Rivers run to the sea and lakes sit in the hollows.
- The world ends in open sea rather than in a wall.
- What you drop in the country stays where you left it until somebody finds it,
  and the world forgets what you left in time.
- A unique you wounded and walked away from is still out there, still wounded.

Monsters, objects and magic
---------------------------

- **389 imported monsters**, including the princes of Amber and the Mythos
  deities. 1013 in total.
- **51 artifacts**, including Grayswandir and Frakir.
- **18 ego types**, including ``(Vampiric)``, ``(Chaotic)`` and
  ``(Trump Weapon)``.
- **Three weapon mechanics** Angband has no equivalent of: vampiric, vorpal and
  chaotic.
- **The Ancient and Foul Curse**, with its cascade intact.
- Random object abilities, pit themes and vaults.

See :doc:`monsters` and :doc:`objects` for the detail.

Tunable without a rebuild
-------------------------

The balance dials live in ``lib/gamedata/constants.txt`` and take effect on
restart:

.. code-block:: text

   lethality:hit-points:73      # percent of base monster hit points
   lethality:armor-class:50     # percent of base monster armour class
   melee:vorpal-chance:6        # a vorpal weapon cuts deep on one blow in this many
   melee:vorpal-multiplier:2
   melee:chaotic-chance:7       # a chaotic weapon discharges on one blow in this many

Setting both lethality values to ``100`` gives behaviour identical to vanilla
Angband 4.2 — a supported configuration, and a useful comparison.

Named here because a features page that lists only what works is a sales
brochure. Each of these has a manual chapter already scaffolded, which is filled
in when the milestone lands.

Multiple dungeons are also still to come.

A **Tcl/Tk front end** is planned for a later phase, reviving the original's
interface on Tcl/Tk 9. There is an irony in it: the original ZangbandTK
supported Windows and X11 and never supported macOS at all, so the Tcl/Tk front
end will be the new port when it arrives, not the other way round.
