I wonder if Noah could use a sort of cycle to improve a bit more. Let me explain - those 2 pairs of wings are "disposable" weapons. Basically one-time use. But they are like a nuclear warhead - you truly don't want to be the target even if only fired once at you. Since they are 4 individual wings, perhaps they can be used for 4 targets. Thing is, since his dark world reached into depths of himself that he cannot even reach yet, perhaps by studying it and seeing what they do, he can gain a clearer picture of his path ahead. His techniques can end up more flawless, with more power etc. at the current level. Meaning his future potential gets elevated even more.
