After completing Forest of Danger, speak to Julian about demon worshippers
Guide
Speak to Marten in the refugee camp.
Complete Stolen Food.
Go to the tunnel complex of the refugee camp, climb the following vine,
then take the following exit.
Use a rope, then jump inside Robert's cabin. You'll get the choice between listening in and barging in. The first option yields the lewd scene Listening in on Liliana. The second option leads to two consecutive fights against: the first against Robert, and the second against a foe with only 1 HP. Three possibilities occur:
You listen in. You learn where is the meeting point between the bandits and the demon worshippers.
You barge in and win the fights. A sparkling spot on the ground allows you to learn where is the meeting the meeting point between the bandits and the demon worshippers.
You barge in and get defeated. The day ends. Come back to Robert's cabin (the front door is now a valid option). You discover no one is inside, and a sparkling spot on the ground allows you to learn where is the meeting the meeting point between the bandits and the demon worshippers.
Go to the meeting point. If you didn't defeat Robert yet, a fight against him will occur. This fight is easier than the cabin fight and yields more money. Losing leads to a Game Over. The day ends after the event.
Speak to Desmond in the Boar's Hut basement (behind the tavern master).
