1. During December 1st-7th, you can talk to Saderon in Cronus City (299,412) to learn the details.
Recently, many people were attacked by a mysterious beast. According to the witnesses, it could be the Ancient Eudemon! Any information about it will be of great value to us. Between December 1st-7th, you can find Saderon in Cronus to discuss the details.
A guard was looking for it a few days ago, but didn't come back yet. It's strange. Saderon told you to find him near the windmill, in the suburbs.
You found the Dead Guard there. Collect the Saliva Sample from his wound and give it to Saderon.
Saderon found that it was the saliva of the Ancient Eudemon. Then he gave you a Eudemon Bait that can lure the beast out of hiding and weaken its power, and also an Empty Container for you to collect its Blood Sample.
Return to the area where the beast will appear and use the bait. You can subdue it after it eats the bait and becomes weak. Then use the container to collect its Blood Sample.
Give the Blood Sample to Saderon, and you will received 1 EXP Ball [B] as a reward. Well done! It will be of great help to the study of the Legion Eudemons.
