I find the rules for Complementary skills from Action 2 a little too stingy - without a critical, they provide a -1 or +1 at most. My houserule is as follows:

Skill Assistance: When applicable (not always), two characters may assist each other on a skill roll. The character who succeeds best has their result modified as follows:

Helper critically fails: Critical failure affects both characters.
Helper fails: Margin reduced by 1.
Helper succeeds by 0 to 4: Margin improved by 1.
Helper succeeds by 5 to 9: Margin improved by 2.
Helper succeeds by 10+ or critically: Margin improved by 3.
