I've run this adventure a couple of times, the last time went like this.
In act 1
the turrets concentrate fire on the guards unless attacked then they only fire on the attacker for that round before leaving them to the golem.
The golem only attacks those who have harmed the ship (ie turrets) or itself ignoring all others. This added to the mystery of the ship and stopped all the players collecting cursed wounds.
I also had that the guards had been using the adamantite axe to pry open the outer hatch so it was held in the doorway and by pulling it free could be retrieved and used.
Act 2
they managed some knowledge checks and where able to open the ghost door without triggering it.
Beyond when the xill first attacked they really panicked especially when one was paralyzed and the xill was fading out with the others covering it but with a dimension stepping wizard freeing them just in time and fortunately stepping to elsewhere in the room thus not through any part of the ship they managed to weather the attack. However with 3 members with cursed wounds and another paralyzed for hours they ended up spending prestige to alleviate these conditions by going on deck and sending a message to the Lodge (this is in Absalom harbor after all) for aid this arrived in the form of an eagle with a satchel containing potions to cure the conditions.
But while they were waiting the rogue had found the door to the dimension door and he and a badly injured fighter had gone through to the helm. They accidentally released the hag who like them was trying to hide how weak they really were, this resulted in some great roleplay
as they rogue called the fighter master so the hag offered him a kiss as a reward for freeing her. Fortunately the others turned up and diplomacy won out and she helped them open the secret door before being released into Absalom.
The final encounter worked well but for everyone concentrating on the plant not the xill, (it must be the way I describe things). They handled the xill with some effort and freed people from the pods as the plant died then had to run and jump from the ship quickly as they heard the ships real engine starting up. It made for a very cinematic ending for a fun adventure as the ship blinked away as the slowest jumped overboard.
