Quest 1: "Evidence of Strength"
Bring 1 of each item to Priest Devin:
| Item | Monster that drops it | Map | Chance |

| Horn of Hell Maine | Hell Maine | Aida | 4% |
| Flame of Death Beam Knight | Death Beam Knight | Tarkan | 3% |
| Feather of Dark Phoenix | Dark Phoenix | Icarus (you need to fly) | 5% |
Items only drop for those with the quest active. To reach Tarkan, Aida and Icarus use /move (see the commands guide).
Quest 2: "Infiltrate the Barracks of Balgass"
You need to kill 20 Balram, 20 Death Spirit and 20 Soram (all "Trainee Soldier") inside the Barracks of Balgass map.
How to enter the Barracks:
- Go to the Crywolf Fortress.
- Talk to the Werewolf Quarrel (x62, y239).
- Pay 3,000,000 zen with quest 2 (or 3) active. Party members within 10 of distance enter with you.
Quest 3: "Into the 'Darkness' Zone"
Kill 1 Dark Elf (Trainee Soldier) in the Balgass Refuge map.
How to enter the Refuge: with quest 3 active, talk to the Gatekeeper inside the Barracks of Balgass. Entry is free.
When you hand in the quest, you receive 30 points and the 3rd class.
Tips
- Set the zen aside: the 3 quests plus entry add up to 25,000,000 zen.
- Mind the reset: quests 2 and 3 require level 400, the same level as reset. Do the quests before resetting, or the character goes back to level 10 and you will have to level again.
- Go in a group to the Barracks of Balgass: the party enters together and the 60 monsters fall faster.
- The 3rd class unlocks the 3rd-class wings: see the wings guide.
