the theorecticall max damage is impossible to do

It requires all yoru heroes to be 18 stars
the first stunner to miss so main dies
all heroes fully sainted
so they have just enough crit saints to always crit the rest must be all maxed gold skill attack
level 115 swords/styaves spirits
with dragon swords/staves an dspirits
level 115 sos and pa
always keep boss stunned
plus a few othe rthings i am sure i am forgetting to get the theorectical max damage

and to do 150m damage in a round would require each hero to avg doing 1.25m damage per hit and go the full 30 rounds. Im not saying thats impossible - but finiding taht hard to believe. My lance has over 91k phy/skill attack and only crits for about 1.2m on the high end
