Begging
Begging is the skill by which one may acquire gold and items from NPC's simply by asking. Since the items seldom amount to much value (even at GM skill level) Begging is typically considered a Useless Skill (though some special items have been made available during Halloween events). Most players who undertake it do so solely for roleplaying.
Note that the use of Begging lowers karma by a small amount.
Training
Activate the skill via macro or skill button and target an NPC. If you do not gain you must find another NPC to target. If you do gain you can target that and every previous NPC again for gains.
