okay, Exertion definitely maxes at 2x ATK
and criticals seem to multiply Damage (not atk) by 3.
my Bob setup was just Kindness + Violence. i found he stays as a werewolf for 3 turns or something so i should have just given him an extra Sylph Rune to trigger Violence after changing. but i did it the hard way by taking hits (made his PROT=0 and no equipment to help)
there's actually 2 numbers that pop up when you get a value overflow.. the first is white then the next is green!
i found the Chick's PDF is around 4-7. let's say 5 since there is some randomness with the numbers.
(999 atk (kindness) x 4.5 (violence) x 2 (werewolf) - 5) x 3 (critical)x 2 (sleep) = 53916
so i'd say Bob can deal 53900 with a max setup (Kindness trick, Violence status, werewolf status, critical hit) on the Chick with the help of sleep, and i actually got 26946 on a non-sleep hit, which is just about half.
and thanks to rnoron's testing with the Violence Rune, we can figure out some other numbers more accurately!
for Valeria, i'm actually not sure where the multipliers are for the Critical Falcon hit. the rune's in-game description says 2x dmg, and Suikoden's descriptions are generally accurate when it comes to rune damage... but -_-
let's just assume the enemy has 0 DEF, then Valeria (Kindness trick, Violence Rune, critical Falcon) can actually only get in the 22470's and hit a sleeper for about 44950.
i'm not going to bother to redo Killey for another screenshot. since i have to max his PROT to work with Warrior to get his ATK to 558 and don't get a spare rune slot for Sylph, it would take hours to get a Chick to reduce his HP again. i could possibly use Blue Gate, but it requires further setup. anyway, we can calculate his max damage..
Killey needs a lot of setup to boost his ATK beyond 499, letting Exertion's effect be more effective than the Kindness trick. 255 ATK, 255 PROT (and maxing TECH/LUK helps with critical hit rate). Master's Garb, 3 Power Rings, max Weapon level. Warrior, Violence, Double-Strike, and Exertion Runes.
on a Chick, he should hit for about 22570's, and if it's asleep, 45150.
so (so far...), the King of damage is actually BOB
