He got hit by 20k with water rst up and a dmg cut, the real dmg from that ougi is near 100k, and no its not the raging overdrive, raging and normal overdrives are the same, you have 5 turns to kill AQ5 bosses, 6 with bp, if you dont, that happens regardless of normal/raging, that being said, its a dps race and thats why stomping AQ4 (aka kill last boss under 5 turns) is a good way to measure your dps to know if your team is going in the right direction or not, dont see it as personal achievements since thats the minimum required in the future.
