[@Bishop] - That's not a bad possibility, and definitely differs and goes outside from the traditional sort and norm that one could configure with Colourless attributes. I imagine that the adaptation quality found within the Colourless standard could be utilized to nullify, or as you say, cancel out an opponent with magical affinities. Say that the adaptation is so critical and immediate, almost on a subconscious level, that it alters resistances and defenses for a certain amount of time to the SOLDIER. Depending on the state of strength within the individual, I imagine, would be dependent to the amount of resistance or how one [or how long] such abilities would be cancelled out.

The CORE value of a Sentinel, in my calculations, will basically not receive as much damage as the opposite who does not have the value applied. The most.. simplistic way I can describe such is that it works in conjunction with the Aeon and the battle scenario within question. The CORE values will be used most during, what I will call, Boss Fights. To keep it from becoming too overwhelming or dampening to the story.
