This is a living effort. Many aspects of the system are unique and therefore experimental. So please, if you have suggestions about how to improve anything, read the graffiti in the monks' quarters and engrave your own comments.
I would only recommend that people who want to help develop and make this world concept better should play around in it. Having written everything from scratch (including the language beneath it) you can imagine that the author has not had a lot of spare time to go adventuring. Yes, that is an excuse for any bugs or shortcomings you may find!
As you may have already discovered, movement is accomplished via direction keys. The up arrow goes north, right goes east, and so on. When you get into the caves, you may also press the center key to use stairways or pick stuff up.
Another way to move around (and perform some special actions) is to click on the exits listed in the View panel.
If you are not familiar with the BYOND client, you may want to experiment with the different methods for entering commands. You can type them in full (the slow laborious method), or you can use the spacebar to expand partial commands. If there is more than one way to expand a command, these choices will be listed for you in the terminal. If you are a mousey person, you can also click on commands in the Verbs panel.
If you want to find out the syntax and description of a command, type it and press F1. You can also hold the mouse over it in the Verbs panel.
There is nothing more disgusting than killing for no purpose. Hunting, on the other hand, is an entirely different matter. The basic idea behind the Night Soil combat system is that you kill to eat and you eat to advance. Such is life.
How you advance depends on how you exert yourself during the hunt and on the nutritional qualities of your prey. If you use brute force, you would most likely want to hunt for good strengthening food like wolf meat. If you are more crafty, resorting to sorcery to snare your prey, you would want something more mentally nourishing, like the sly blue meanie.
The use of tools such as armor and weaponry is a matter of practice. And the best sort of practice must involve somewhat of a challenge. An angry hornet is a much harder target than a stealthy spider. But once you have mastered the art of swatting hornets, even they won't provide much chance of improvement. Of course you can always try striking them with a chop-stick if you want a challenge!
p.s. Please note that this is not the only MUD written in DM. It is not even the best MUD written in DM. In fact, I invite and encourage you to explore this and all the others and then try your hand at creating one yourself. You are welcome to steal ideas from here, providing you forget where you got them from and think they are totally original and divinely inspired.
p.p.s. Since this world utilizes the BYOND MUD code base, it is a simple matter to connect additional worlds, creating new lands to explore without running into the single machine network load barrier. If you would like to become part of that effort (or have a machine to run a world on), don't be shy!
