Thanks a lot Raze.

My first answer was :
[color:"orange"] Tu peux éventuellement vider complétement ton inventaite et ne conserver que l'or, les bières et les cordes.
Tu peux reprendre une ancienne sauvegarde et réessayer cette quête.[/color]
You can make your inventory empty and just keep the gold pieces, the beers and the ropes.
You can also load an old save game and play again this quest.

Now i am going to tell him to put the silver armour in the inventory and to be careful with stuff which can hide other important things in his inventory.
