The Forced generosity trading skill is actually a collection of many different tactics. Each hero has their own unique strategies to wring more money out of traders, but only the truly masterful can say they are experts in forcing generosity.
Some examples that have been proven to be very effective include; begging, pleading, asking nicely, puppy-dog eyes, menacing glares, batting eyelashes, displaying pictures of poor children and claiming to be related, displaying signs saying "will work for food", forging certificates of authenticity to pass off modern equipment as valuable antiques, and/or kidnapping and threatening the trader's family.
Note: do not attempt this with an arms trader. Why would you steal from the man with thousands of ways to kill you? You wouldn't or shouldn't. So don't!
