When you cremate the shade remains, you may be rewarded with either coins or shade keys. These keys will be made from any one of 4 different metals, and 5 different colours. Each combination of metal and colour on a key will open a specific type of chest in the catacombs, and will disintegrate once you've unlocked it. The key can also be used to open all doors of the same or lower type of metal, improving from bronze to gold, and will not be used up when doing so. There is a unique gold type of key that is used to open special chests. * File:Gold key.png Gold key
