Activate daily quests—for instance, by placing a Sura NPC at the entrance to the Orc Valley for each kingdom—requiring players to kill a certain number of monsters (chosen randomly each day) or destroy Metin stones.
Alternatively, the task could simply be to gather specific ores or herbs.

Implement a reward shop within that Sura NPC.

For example, earning 100 quest points in the Orc Valley could allow you to buy items like a Blood Sword +4 or a fan with a guaranteed random bonus (1–3 slots)—limited to once per day.

You could also obtain a 1-hour item that boosts damage in the Orc Valley by 5%, or spend a larger amount of points—say, 500—on something else.

For players who complete the Orc Valley quest daily for two or three weeks, there could be a chest costing 5,000 points containing useful items like Blessing Scrolls, Magic Stones, Cloaks of Bravery, etc.

This system could be implemented in every zone—such as the Desert, Ice Land, Fire Land, and so on.

In the long run, this would be great for players; it engages them with special features that ultimately make the game more fun to play.
