Lucy and Lucius managed to reach the third floor of the Array. That was already way more than Darian expected. Their blessing had insane potential, but everything depended on their opponent's karma or how important their goal was. Against the illusionary enemies from the Array, they pretty much had no blessing power to use.
Even so, they made it to the third level by relying on their brains and raw ring power. That alone already showed how skilled they were. The main thing was that both of them were pretty smart and figured out the clear attack pattern those enemies had.
When they got back home...
After that scene Lucy witnessed in Darian's room, she pulled Niara away from him and had a good talk with her. Lucy knew her brother, and she also knew a bit of Niara's story from their time in the other universe.
