[So, do you better understand the 4th Idle Benefit now? Contrary to the subtle 3rd Idle Benefit of Skill Fusion, it is definitely more extravagant, no?]
"...Yes," replied Cassius, his voice failing to fully conceal his awe. "This Idle Benefit will certainly change a lot of things, but the question still persists: how do I go about unlocking this Idle Benefit?"
Answering his question, the Idle Evolution System said, [You just need to complete Main Quest #5, which will appear soon after Main Quest #4 is completed. One of the rewards for completing Main Quest #5 is the 4th Idle Benefit.]
"I see…"
Cassius speculated just what sort of Quest would follow up something at the A+ Rank, eventually leading him to only one conclusion. "This Main Quest 5… It will be of the S-Rank, won't it…?"
[That is highly possible!]
"Hmm…"
