Wow... I didn't expect to earn over a million gold pieces in one chapter alone...

This is probably the first time I managed to earn over two million gold pieces in an IE-game. Looks like I can aim for three million gold pieces in my next run-through.
Just like my first run-through on Core Difficulty in the first IWD game, my party entered the Final Fight when they were only Lvl-16 or so. Due to the presence of the allied monks, I switched to manual combat and man... it was a massacre for the Legion.
By that point, I was overflowing with high-level scrolls and items and it was merely a matter of literally throwing everything at the evil beings while my Cleric was on standby to cast Mass Heal. Mass Heal is most probably one of the most broken spells ever conceived of.
I probably felt more tension fighting the Silent Six than the final boss fight.
Second run-through will be on Hard Difficulty, and a stress test of the AI scripts.
Cheers.
