The following chapter of our guide to Assassin's Creed Odyssey describes all the side quests available in the Achaia region. Here, you can complete only two side quests: The Dunce Conundrum and Another Kind of Poetry.
The Dunce Conundrum
How to start: North, near the docks in Achaia.
Description: Speak with Demokritos. The man tells you to find and bring him three mysterious items. The first one is found in Argolis, near the town's center. The papyrus lies on the table in one of the rooms.
The next item is found north from Thera island. Jump into water and dive (watch out for the sharks). Find the chest and open it.
The third item is in Lokris.
Go back to Demokritos and answer his questions. Your answers don't matter - choose whichever dialog lines you like. Rewards: 10,919 XP.
Another Kind of Poetry
How to start: After completing "The Dunce Conundrum".
Description: A short and simple quest. Follow Demokritos - you will be attacked by a group of enemies. Kill them and then speak with the man. You learn that his beloved has been murdered. Try to cheer up the scholar. Rewards: 18,500 XP.
