Editing Gladius et Aegis: Rolling with the punches (section)

===Other Sources of Bonuses and Penalties===

As a rule of thumb, the GM should apply other bonuses and penalties based on things that affect the character and his capabilities, rather than the target of the task. Generally this should be +1, +2, -1 or -2 per circumstance: any more than this, and its probably time to be thinking about automatic success or failure.

An example of things that might effect capabilities include confidence, inebriation, equipment, clothing (such as a nice suit when at a job interview).

Things which affect the task instead don't cause bonus or penalty dice, but instead affect the difficulty. 

An example of things that might effect difficulties include range, visibility, size of targets.
