In some cases, a roll may be needed which does not conform to a specific Skill. In the above Example of holding on to a rope, the Game Master may require a Strength roll to just keep holding on. When performing an Attribute Roll, the player counts the Attribute Scale as the Skill Rank, rolling a number of dice equal to his Scale, then adding his Aptitude and his Scale to the highest result. Attribute Rolls are normally a little more difficult than Skill Rolls.
