Ease Factor

In Ars Magica, the Ease Factor is the minimum number a player has to roll (after modifiers) in order for a character to succeed at a task. The term is a little counter-intuitive because more difficult tasks have a _higher_ Ease Factor.

Ease Factors are commonly multiples of 3, but that is just a convention, not a hard and fast rule.

Example of Ease Factors in Play

A character with a Strength of +2 tries to force open a barred door. The storyguide tells the player to roll a Str Stress Die against an Ease Factor of 9. The player rolls a 7, which is modified by the character's +2 Strength, for a total of 9. Since this equals the Ease Factor, the task succeeds: the door opens.
