RULE-FLAT-EXPERIENCE
Normally the mud gives out listed experience for a mobile if the mobile is level levels lower than you. If the mobile is lower or higher than 10 levels below you a penalty or bonus is awarded. This is designed to reward people for fighting more difficult monsters. The penalty/bonus works like the following:
... and so on ... 12 levels lower ... -2% penalty 11 levels lower ... -1% penalty 10 levels lower ... 0% 9 levels lower ... 2% bonus 8 levels lower ... 4% bonus ... and so on ...
However, with the Flat Experience rule, all exp handed out is the listed exp, regardless of your level compared to their level.
