Unlike Fein, Voli couldn't feel the elemental lights at all. Yet, he instinctively uses them every time he activates his ability. Voli doesn't understand the principles of the elements like Fein. He only knows how to use them. Just like how normal people used electric fans and vehicles without understanding how it works, unlike the inventors who created them... Though they can use the finished-product normally. Fein doesn't only know how to use the element, but also knows their principles!
This is the advantage of understanding the law of elements. Others could use their elemental abilities normally, but don't know how they work, so they can't replicate it or create other applications. Unfortunately, the only creature with high comprehension could sense the elemental lights and understand the laws. At least, Fein only managed to sense the lights after his talent had reached S rank.
