Men are monsters found all over Gielinor. There are several in and around Lumbridge, where you first start. As such, they are likely to be among the first RuneScape Classic NPCs you encounter, and for many players they are the first monsters that they will kill. Men are commonly trained on by all combat levels. Many players also kill them for the unidentified herbs, which are commonly dropped and are 5K each right now.
They can be pickpocketed at level 1 Thieving. When pickpocketed, they yield 3 coins making them a great source of money for new players.
