"Likewise, the racial affinity brings appropriate result upon collaborating with the innate affinity. If opposite affinities are present, like Fire and Water, then the result would be unsatisfying. If both affinities are the same, like Fire and Fire, then the explosiveness increases by many times.
But, if the innate affinity and racial affinity are complementing each other, which is rarer, like Water and Ice, and Strength and Agility, then it makes the most powerful combo. A point to note, the racial affinity only attributes its characteristics to innate affinity unless the racial affinity is an attribute type. Then the audience will witness the hybrid form of an element and an attribute.
An example is the Fire and Wind affinities which can create firestorms. Ice and Water create flexible Ice needles that switch between solid and liquid states. Defence and Stone affinities make up the best and impenetrable walls."
