Swords and Shields

Each creature you have will have either a Sword or Shield attribute and can be assigned (by you) to a Red, Yellow or Green group.
The color groups have no meaning other than your own grouping. You may decide to group by Element, Distortion, Strength/Health ratio - whatever you like - they have no influence in the game.
The attribute is different and tells you whether the creature will get a bonus when it is either attacking or defending in certain scenarios.
