Note: This side-quest is first available when you visit Bloodstone for the first time. You must visit and purchase Brightwood Tower in Brightwood.
After purchasing the building, make your way to the very top of Brightwood Tower, open the chest for a journal, shoot out the window opposite and kill the gargoyle on the outside wall and then sleep in the bed. You will be teleported to a new zone as a child.
Follow the path to an open area with a chest sitting in the centre. Open the chest and a message will pop up on the screen. It is from the chest and it will tell you that its name is Chesty and it wants to play a game. Now its idea of a game is to do a Crucible style challenges in which you need to take on groups of increasingly difficult bad guys. Anyway, once the message has popped up, the chest will disappear.
Now there are five different locations that the chest will appear and you can follow gold dust to the chest and open it as it appears. Each time you try to open the chest; it will summon enemies to attack you before disappearing again. He will do this five times, resulting in the following challenges:
- First challenge: Beetles
- Second Challenge: Hobbes
- Third Challenge: Hollow men
- Fourth Challenge: Banshee and hollow men
- Fifth Challenge: Balvarines
After the fifth and final challenge, Chesty will give you your reward. Go through the door behind the chest and sleep on the bed here to complete the quest.
Note: for completing this quest you will earn the following reward/s:
- Renown: 3,000
- Trophy: Son of Chesty
- Gold: 100,000
- Item: Diamond
