The Log will become handy when you get to the Count Bram’s castle. The Fire Room is too dark and you will need some light to find the key of the armory room.
How to Get the Log
When you arrive to the Count Bram’s place, you’ll see Christopher sitting on the ground. Jump up onto the rocks above. When you’re done taking care of the warewolf, the log is in the left rock but you can’t reach it because of the thorns in between platforms. So run to the right and jump up the steps. Make your way to the left by jumping from rope to rope. When you land on the large tree branch, another werewolf appears and knocks you down. You both fall, but when you land you’ll get the Log.
