How to Attack Monsters.
If you place your cursor over a monster, the cursor will change to a sword icon. If you then click on the monster, you will attack. If you hold the Ctrl Key as you click, you will continuously attack the monster.

You will gain experience along with a possible item drop as a reward for defeating monsters. If you prefer a greater challenge, rare item drops and more experience, try defeating a boss monster
Utilize Skills to Help Defeat Monsters.
For a more convenient way to use skills, simply drag the skill to the hot key window and use F1~F9 for the assigned skills. With this, battle will be much easier.
