In a split-second decision, you dive towards the left chest. You scrabble desperately to open the lid, but it seems to be stuck fast! The troll roars again and charges at you, axe held high above his head, ready to cleave you in two.
The lid of the chest springs open and you reach inside to pull out...
... A chainmail vest. This is the wrong chest!
The axe hits you squarely in the chest, spurting blood everywhere. The last thing you see as you fall to the floor is the troll standing over you.
You have failed to retrieve the diamond. Your journey ends here.
