Quick summary

• Biologist quests come from Biologist Chaegirab and Seon-Pyeong, and they improve your character permanently.
• The chain runs from level 30 to 94 in ten steps. You must finish one before the next starts.
• You can deliver one item per day, so the chain is a long grind rather than a single sitting.
• Each step asks for a material plus a soul stone, and pays a permanent bonus on completion.
• Gameforge lists biologist quests as one of the quest types that stay relevant long after the early levels.

Where to start

You take these quests from Biologist Chaegirab and Seon-Pyeong. Two rules shape the whole chain:

• 1 item can be delivered in 1 day and no more.
• You have to finish the previous quest before the next one starts.

Gameforge's beginner guide names the biologist Chaegirab as the central NPC for these quests, and notes that Baek-Go may play a role in certain steps or completions.

The chain

• Level 30, The research of the biologist 1: Orc Tooth x10 and Jinunggyis Soul Stone. Permanent +10% Movement Speed.
• Level 40, The research of the biologist 2: Curse Book x15 and Temple Soul Stone. Permanent +5% Attack Speed.
• Level 50, The research of the biologist 3: Demon's Keepsake x15 and Sagyis Soul Stone. Permanent +60 Defence.
• Level 60, The research of the biologist 4: Ice Marble x20 and Aurtumryus Soul Stone. Permanent +50 Attack Value.
• Level 70, The research of the biologist 5: Zelkova Branch x25 and Gyimoks Soul Stone. Permanent +10% Movement Speed and +10% Damage reduction, which the wiki notes is not defence.
• Level 80, The research of the biologist 6: Tugyi's Tablet x30 and Tugyis Soul Stone. Permanent +6% Attack Speed and +10% Attack Value.
• Level 85, The research of the biologist 7: Red Ghost Tree Branch x40 and Forest Spirit Soul Stone. Permanent 10% Damage reduction from other players.
• Level 90, The research of the biologist 8: Leaders' Notes x50 and Leaders' Soul Stone. Permanent +8% more damage toward other players.
• Level 92, The research of Seon-Pyeong: Malevolence Jewel x10. A choice of 1,000 HP, 120 Defence or 50 Attack Value.
• Level 94, The research of Seon-Pyeong 2: Wisdom Jewel x20 and Beran-Setaou Soul Stone. A choice of 1,100 HP, 140 Defence or 60 Attack Value.

The wiki lists the last two rewards as an either-or choice, so read them as a pick, not a penalty. Every other step in the chain pays a fixed permanent bonus.

What the prizes are worth

Movement speed, attack speed, defence and attack value are all permanent once the step is done, which is why the chain is worth finishing even when the material is annoying to gather. The level 70, 85 and 90 steps lean toward player combat, with damage reduction and extra damage aimed at other players.

Planning the grind

The one-item-per-day cap is the part that trips people up. Ten steps at one item a day is weeks of real time, and the materials climb in count as the chain goes on, from 10 Orc Teeth at level 30 to 50 Leaders' Notes at level 90.

Gameforge's beginner guide tells new players to keep biologist quests in mind long term, and lists not mixing them with your first levels as one of the common beginner mistakes. The quests start at level 30, so there is no reason to touch them before then.
