So right now I'm in a difficult situation with my character.
I've reached level 15 and my battle power is 1101. I can go to the final quest, however, Nex Aelio is impossible to defeat. I simply can't kill it at the second phase and I had to abandon the quest completely.
However, it is also impossible to get any stronger, because I can't go to any areas to grind. The factory ruins have only level 10 enemies which now give me 1 XP each and as far as I know, until the final quest is completed there is no way to select the "rank 2" (level 15) areas.
In other words, I can't grind to reach higher levels and get stronger, but with my current setup it's impossible to kill Nex Aelio because he insta-kills my character during the second stage of the fight. I can use only one Half-scape Doll, even though I have several in my inventory. Can it be that the only way forward would be to actually throw money at the game, buying Half-scape Dolls with AC at every death until Nex Aelio is finally killed? What if I'm killed dozens of times? I don't have that much money.
Any tips on how to overcome this situation would be welcome.
