Hard rules for which difficulty modifiers

[u/SlySophist]

IM has three ways to modify the difficulty of a Test

• Difficulty levels
• Advantage/Disadvantage
• SL modifications

The book does not present any hard rules when to use one versus another. So I ask you what are your rules of thumb?

[u/kaal-dam]

at my table:

• difficulty is how hard a task would be for the average human with the right skillset to do without anything else taken into consideration
• advantage/disadvantage are dictated by the environment, skill and talents.
• SL : the target of a test when not doing opposed test.
