Buffs

Buffs are permanent or temporary increases in an Attribute or in the power or efficiency of a System ability. For instance, if you eat meat from a very tough monster, you may gain the buff "Well-Fed," which grants a temporary boost to your Constitution and therefore your HP.

The opposite of a buff is a debuff, which is a reduction in an Attribute or the power or efficiency of a System ability. For instance, if you reduce your Mana pool below zero, you will obtain the debuff "Mana Shock," which prevents you from using any System ability that uses Mana until you have regenerated at least as much Mana as you went below zero by. (For instance, if you go to -9MP, you cannot use Mana, for anything, until you have not only gotten above zero, but back to 9MP.)
