Manual:Game Mechanics/Introduction

This manual explains how the basic game mechanics work and what should be considered for building a good and balanced world.

Dice Checks

In DikuMUD as in many other game systems, many checks for success or power of skills and spells are determined by dice rolls.

An open-ended 1d100 roll (1d100OE) forms the basis for most checks. The open-ended rolls works like this:

If you roll 96-100, roll again and add to the previous result (repeat if 96-100). If you roll 1-5, roll again and subtract from the previous result (repeat if 96-100).

A check is generally successful if: (skill + 1d100OE) >= 100.

For example, if your skill is 20, you would generally need to roll 80 or above for success.
