Begging Skill
Begging lets you walk up to NPCs (vendors especially) and beg them for money. If they have any coin on them they may hand over a fistful of gold. To use the skill, activate it from the skill list and target the NPC. You need to look poor and harmless, your hands must be empty and you must not be mounted.
Using Begging over and over will take you all the way to 100 skill. There is no need to change your strategy as the skill goes up.
Begging has very little use these days. Begging things off other players is far more effective.
