NPC quests
Besides the evolution quests, which change your class, there is a second system: NPC quests with dialogue, which pay zen and experience.
Who gives them
The Shadow Phantom Soldier. He is spread across the towns — Lorencia, Devias, Noria, Elbeland, Arena and Arkania.
Requires level 50.
How it works
Talk to him and he talks back. Each quest asks for one thing — kill a number of a certain monster, or bring an item — and when you come back, he pays and opens the next one.
It is a chain: one quest unlocks the following one.
What it pays
Zen and experience. No items.
The experience is useful early on, and the zen is what serves most — it is money without depending on drop luck, and money is what raises items.
What is not enabled
The Gens system is off on this server. Its NPCs — Gens Duprian Steward and Gens Vanert Steward — exist in the game, but are on no map and give no quest.
If you saw Gens mentioned in some guide, it is from another server. See what is different here.
