Ran this yesterday with a party of 4 x Level 6 players and had a blast! This is a very tight and atmospheric one-shot with a great location and backstory. However, as written a lot of this backstory can easily get lost in a series of combat encounters. Whether that's up your alley will depend on the group. Having said that, it doesn't take too much effort for a DM to push the social side of the more interesting encounters.

I ran this one-shot for a group of kids over the Christmas period. They loved the ocean theme and and the various set-pieces - Nimbly talked thier way out of the pirate fight with some great role-play. Sadly experienced thier first TPK in the final fight - though they did manage to stop the summoning! As a DM it was very easy to run with clear information - the one page scenarios in particular meant I didn't have to waste time shuffling pages. All in all, a great adventure - recommended!
