Idk see how you fo 9999 damage and the start of a game that dont even make sense...unless you became insanely over leveled or its a bug or whever you are these enemies have big HP pools...and you can do over 9999 damage i seen somebody do 246k damage on youtube unless that was a bug or mod...and who the fukk is maeve
meant to say maelle, the teenager.
I think 9999 is the cap. They definitely modding if they went higher or there is some kind of mechanic change in the late game. I have had to use multi-hits to get the full potential of my maelle because she was hitting too hard and basically lost damage in her one shot moves.
Use the virtuouso stance weapon and get it to 9 first before the rest of the party. use the passives that give a first turn boost and with no buffs, do 9999 opener. After first turn, you will need powerful to hit 9999 again but she constantly does it, especially on counters.
