Rule book page 2 says about the crystals that
green - value of 1
yellow - value of 3
red - value of 5
But all rules says that crystals are one victory point per crystal, or did i misunderstood the rules? The only page i have found that describes the value of crystals is page 2.
During the setup do you place crystals in each region blingdly or do you place only green crystals in each region (and later on game draw crystals blindly from the bag?)
You never draw crystals blindly. You place the amount of crystals listed on the board space into the spaces during set up. And add crystals when tokens and events instruct, and at the beginning of battles.
The crystals have values just like money in other games, to help you have large amount of crystals in an area, with out having a large number of physical crystals to place there.
If you need 7 crystals in a region you can put 7 green, or 1 red and 2 green, or 2 yellow and 1 green.
