The latent ability provides a bonus to his sharpshooting skills, as well as gives him some insight into future events. However, it's balanced out by two flaws: Cassandra Truth and a tendency to see worst-case scenarios, making him naturally paranoid. His tall tales serve two purposes: in-universe, it's a method of coping with and relaying his visions in a way that doesn't get automatically rejected by others. On a meta level, meanwhile, it's a way of challenging the GM, who has to eventually translate his stories into the campaign in some fashion.
