This is like some kind of strange rm2k gambling game. I could seriously see people laying bets on an ‘automated’ version of this… What an odd idea you had!
Missed exactly one attack, on level 48 - with one party member and one enemy left, then went first on next turn and continued. Then all good outcomes till 55, when 3 enemies all went first, killed 3 characters, and then one went first in the 2nd turn- game over.
I still had lots of resources left, too.
