Simple Twenty Rules

by DaveF, Oct 2004

The following rules follow the ideas of d20.

Basic Task Resolution System

These rules assume a standardized system for determining the success or failure of any given task. That system is:

           d20 + Modifiers vs. Target Number

The Modifiers and Target Number are determined by the type of task.

If the result of the d20 roll + the Modifiers equals or exceeds the Target Number, the test is successful. Any other result is a failure.

     TN       Type of Use
      5       Simple Task, Skilled person should always succeed first time
     10       Ordinary Task, Skilled person should always suceed with a few tries
     15       Average Task, Skilled person should always succeed afer a
                  short time (ie take 10)
     20       Hard Task, as Average Task but also required tools
     25       Difficult Task, as Hard Task but a skilled person needs to spend
                  concidrable time to do (ie take 20)
     30       Imposible Task even for a skilled person
