To survive in the Classic Conquer world, you will have to fight many monsters (and players!).
You will obtain experience (EXP) every time that you damage an monster, and also when you or a teammate kills a monster.
Sometimes after you kill the monsters, they may drop some money/items, pick them up because they are your main sources for money at early stages. If a player is killed, he/she may drop items or money, too.
