Every model has an affinity with one or more of the Goddes Crystals of Crystalia. A model may gain greater benefits from equipment or game effects if they share an affinity. Conversely, a model may suffer penalties if they do not share an affinity. Models with more than one affinity gain any bonuses or penalties if either one of the affinities match.
If a model has affinity with two colors they benefit or suffer the effects of the affinity if either of the colors match.
The colors of the Crystals are:
Citrine = Yellow
Emerald = Green
Ruby = Red
Sapphire = Blue
