After crafting weapons for Isabella and Sylphy, Jiang Fei still had some Valium to spare but it was not enough to make Hua Mulan a spearhead. Ariel and Nina had no need for weapons as they fought using energy projections and shields, not physically. Having a weapon would not grant them any advantage.
Isabella, being a truly powerful fighter, had only become much stronger than before, living up to the title of the Destroyer. Sylphy on the other hand was not as… destructive as Isabella could be. In comparison, Isabella with her domain ability activated would be akin to a nuclear bomb. Sylphy, on the other hand, was like a surgeon. She might be as powerful as Isabella when it came to dealing with Unknowns, but when it was a battle against Metahumans, Sylphy was just like a Death Reaper; a silent entity with no presence that could reap your life away without you even knowing it.
