I’m guessing strongest single strike is the single strike that was the strongest and highest total damage is the highest amount of damage you did in total.

Total damage over the entire battle vs strongest single instance of damage

Let's say, you're fighting the Crab boss in Stygian Onslaught with Ineffa, Columbina, Neuvillete and Xingqiu. And in the course of the fight, Neuvillete hits 300k dmg once. And nobody else comes close to it. This would be counted as 'Strongest Single Strike'.

But let's say Ineffa has more consistent dmg through the fight and has a total of 3m personal dmg, more than anyone else in the team. This then would be counted as 'Highest Total Damage'.

Strongest single strike is the strike that was the strongest

Highest total damage is the total damage that was the highest

Highest single instance of dmg vs collective dmg of the character.It's One-big-shot vs collective points?Weird example but think of it as widsith vs prototype catalyst on Neuvillette.The latter is collectively better,the former is higher dmg shots
