He tells Dreevale to subtract 20 from his score. Dreevale rolls 91, which is greater than his modified score of 20. The Gorlian punches Dreevale. Under normal conditions NPCs who work for a character will always obey that character. If characters try to give orders to strangers, the referee must decide how likely the stranger is to obey.
Leadership also is used to bargain with NPCs.
The referee should not let characters with high Leadership scores trade junk for valuable merchandise, but a successful Leadership check will get a better deal for the character, or convince reluctant NPCs to deal with the character. Characters can bargain for information as well as merchandise. More information about the effect of Leadership on NPCs can be found in the rule section on NPCs. As characters adventure, they learn from their experiences and improve themselves through practice. The referee hands out experience points at the end of an adventure to reward characters' performance and success.
