When you Create a Gate, you may chose and place either an available Colour Gate or a normal Gate.
You can ONLY Create the Glow Gate if you already Control another Colour Gate.
You do not have to Create the Gate of your Faction color. So Crawling Chaos can Create a red Gate.
A Colour Gate acts as a normal Gate during the Gather Power Phase.
At the START of each Doom Phase, roll 1d6 and consult the appropriate tab of the chart below:
Beginning with the Starting Player, and continuing in turn order, the first player who does not Control a Colour Gate must select a Colour Gate from the Pool (if available) and replace one of his normal Gates with it. At most one player does this.
GLOW: The Gate’s Controller chooses any other Colour’s effect from Feasting.
GLOW: The Gate’s Controller chooses any other Colour’s effect from Madness.
GLOW: The Gate’s Controller chooses any other Colour’s effect from Blight.
The player with the lowest Doom total may select 1 Colour Gate anywhere on the map and replace it with a normal Gate. On a tie for lowest Doom, all tied players do this in player order. When finished, reroll the Colour die. On a second roll of 6, nothing further happens. On any other roll, consult the appropriate column of the chart.
