I made the necropolis 100% using the mod. I used attack configuration 2 using hercules r5 lit and aegon r5 lit. for defense I used 15 just to reduce the cost of reviving. After farming Aegon's 999 charges, reduce Aegon's attack to 1 and keep his defense at 15. If you want, add an amplifier to increase his damage in other fights. Do not use amplifiers to fight Hercules with attack 2 as his damage is very high and the fight will end very quickly. Ideally, fights should have an average of 250 hits and the use of revive is also necessary to simulate that you are actually playing the normal game. For each fight, use between 1 and 2 revives and when you reach grand master, use at least 5 revives.
And most importantly, don't make several lines in a single day. Do a line every two days. Don't speed up the process. Don't worry, everything will work out and with as little expense as possible.
