The Balrow family didn't have much intel on the higher layers. The main issue was the lack of suitable experts willing to spend entire centuries exploring those areas and clearing various trials.
Great Builder's tests were also far above normal standards in terms of difficulty. The expert was a monster, so only monsters could obtain his resources.
Noah felt partially out of place in the fifth layer. In theory, only existences in the liquid stage could overcome the tests there, and his battle prowess had yet to reach that level completely.
However, Noah wasn't alone. The whole Legion and his organization were with him.
Wilfred and Divine Demon were in the liquid stage. King Elbas and Second Prince were geniuses of the inscription field, and the various magical beasts and hybrids had nigh-endless resilience. Noah could rely on his companions to take care of most of the tests.
