Ive been trying to get the 3m achievement and im having alot of difficulty.
Natalie is currently level 32 with 1434 magic attack. I have all the correct gear for her.
What I am doing:
Fighting Golden Dragons just before the Cat boss. I use Screamer with Matt in the hopes of debuffing the dragons magic def. If it is, then I wait till the next round. Next, using Matt I use some food on Natalie. I then use Absolute Zero with Anna to freeze the dragon. If all of that works, I then cast Black Hole with Natalia.
Does this all sound correct? Im not getting close to 3m, my only guess is that I just need some more levels.
Use scream twice so the dragons are debuffed down to 50 for magic. Also use Debilitate twice to weaken their overall defense. Then you need to make sure Natalie has brave status so she can get a critical hit. You for sure won't get it if it's not a critical hit. Also make sure the gear is correct. Dark Bauble, Death Scythe and School Girl Uniform give her the highest magic and dark damage possible.
