In Chapter 3 you will get to a small town area. You will want to explore and kill all the enemies. There are many useful items found like the crossbow and the flash bolt. The flash bolt is found on a watch tower. Any enemies not killed will join in the boss fight so make sure to clean house. When you trigger the boss in the barn use 2 explosive bolts and a few shot gun rounds if you have it. Now switch to flash bolts on the crossbow and sneak kill him when the prompt appears. Repeat the last section until he is dead. You can craft move flash bolts mid-fight.
