MU Online quests
In classic versions, the main quests are the ones that unlock class evolutions and new skills. Each starts with an NPC and requires a minimum level. The server's quest file shows exactly who gives each quest, from which level and for which classes.
Quests in the server file (Season 4)

|---|---|---|---|
| #0 | Sebina the Priest | 150 | Dark Wizard, Dark Knight, Fairy Elf, Summoner |

Read from Quest/Quest.txt (Season 4). The NPC name comes from the same package's monster index.
Reading the table
- A quest can have more than one step; the table merges steps by quest number.
- The minimum level is what you need to start that quest.
- The listed classes are those allowed to do it; Magic Gladiator and Dark Lord only appear in the file's last quests.
Where the NPCs are
Map pages list each map's NPCs, read from the spawn files. If you cannot find the NPC, check whether your server moved the quest or replaced it with its own system.
