We also finished a Sea of Blood campaign, with some house rules to make it playable. We heroes prevailed, but were quite lucky: the OL missed his first 8 raze rolls, and during gold age, as cities were under pressure (3 razed and the last 2 sieged), we got a rumor with a golden hourglass that stops time for the OL for 3 weeks.
Two house rules we played with, which seemed necessary, was that Lieutenants who fled were stunned: they could do nothing the following week. Also, whenever we succeeded in crossing the map with the revenge, it was considered a breakthrough, with identical results as a Lieutenant flight. It is not that difficult to achieve (once we succeded with only 1 survivor though), but usually it gave the OL free conquest for the price of a liberated city (weekly conquest + 0-3 kills). Once the third Lieutenant appeared, even these house rules became useless, because freeing one city while 2 other ones are under siege brings you nowhere. From then on we concentrated on entering dungeons to make the campaign progress.
However, these two house rules brought us closer to the end of the game, which, with the help of the golden hourglass, pulled us through.
Therefore I suggest adding the bolded part to the text on page 27:
Players and lieutenants may only flee off of the opposite side of the map they appeared on. They can no longer move off the “sides” of the map, only the edge opposite from their starting edge. Lieutenants who flee from an encounter are now moved to their starting space on the map, and cannot be issued orders the following week.
We also had a good tentacles rules. If I remember well, the head moved first with the tentacles following it; when the head had ended its movement, tentacles were placed as they were placed when the head started. Then the tentacles could move individually, but never more than 3 spaces away from the head. Tentacles could attack the revenge (1 silver die per tentacle during silver and 1 gold die during gold, 2 surges gave 1 threat), so there was no problem if the heroes stayed out of reach of the tentacles, as the Kraken could always take on the ship.
We also had the home rule that Dallak couldn't be used as a port, which I see has made it into the FAQ.
The new reverse Divine Favour rule seems excellent.
Thank you for having worked (and for still working) on this final FAQ.
