It really isnt a cheat ability. He got it by utalizing the world's available resources with one of his racial bonus traits. While his skill may be special, it is not rule breaking by any means.
"Cheat abilities" are things like enhanced growth (ex: +4x XP and bonus stat points), utalize any magic by simply thinking it, infinite mana/stamina, instantly learning things (like all languages, or suddenly aquiring any and all skills just by looking at them once), etc. Basically, if it offers power, effeciency, something that does not currently and would never exist in the world, and/or resources, but with no cost or effort from your part, it can be considered a "cheat ability".
His power is a racial bonus, and was absorbed through the cost of magic stones. Even then he still has to put in effort to even properly use it.
