Bring the Poisoned Man to his Friends is a side quest which can be started when traveling between the areas of Athkatla in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition. In one random encounter between areas, you will come across a band of thugs attacking a man. The thugs will turn on you and you must defeat them.
  • The poisoned man will ask you to bring him to his friend in the Athkatla Docks to the building most southwest of the area.
  • Bring Renfeld's Body to Rylock in front of the building in the southwest. The man will then reward you.
  • This quest is prerequisite for Find out What Happened to Montaron, after you bring the body to Rylock (oddly, there seems to be no timer in this part), attempt to head back north, Xzar will appear near the stairs to the Sea's Bounty Tavern.
