Summarized %/s List

30 of the 45 entries gain more than a 50% damage increase with 100% Boss Damage. I'm not sure where you're getting your number from. It's never exactly 100% increase because every class has at least some form of total damage with Hyper Skills. Luminous is the class that gains the most from Boss Damage because their only source of Total Damage is from their Reinforce Hyper Skill, and their Level 200 Buff.

The values aren't exactly linear because there's usually instances of something random occurring or a rounding error that I haven't bothered to fix because it's so small. For example, the difference between 200%-100% Kaiser and 100%-0% Kaiser is 11413 and 11364 (less than 1%). This is a result of Regained Strength's activation chance being treated randomly. It would vary even more significantly across classes if I made Critical Hit Rate use an RNG as well. I currently don't do this, but I might in the future. It currently serves no significant value, but using an RNG for things like FA provide accurate values for additional hits, etc, rather than adding activation rate * damage cap every time an attack occurs.

dark knights only gain +20% total damage too from reinforce, just stating it in the weird case you were doing something weird in the math.

this brings me a question i had never thought of though, when you state 100% boss and 200% boss, is this being added to what a character already has, or it's the threshold? example of what i mean, hero at 100% boss, would he have 120% boss (+20% from boss killer) or just 100% boss?
