So I did it in 13 as I promised; the new screenshot is attached:
Difficulty - Impossible
Class - Warrior
Level 30
13 days
100 quests completed, 1 unfinished
28,468 leadership
37 Attack, 30 Defense, 15 intellect
Rats eaten: 0
Score: 1612
And you properly guessed what the unfinished quest was
That's 2 days that one cannot afford when playing for high-score; And no, I didn't skip anything else. Just in the 13 days game skipped a few things in Murock so I could save those 1:17 that were pushing me in 14.
