あの人は千の魔法を使いこなす最強の魔法使い
I took this sentence from a manga. in this sentence the noun that follows 使いこなす directly is not the one that it directly modifies but 最強. In such cases should the て form or the normal form be used? I am under the impression that if the word following it are nouns/ adjectives, it would be the dictionary form while if it's another verb it should be the て form. Is it correct?
