The Everjust is confusing with 4 cannons instead of 3.
Personally I think the comment in Dorrian’s name is unnecessary. Especially because it made me think the ship linked to two crew, one called “Master-at-Arms” and one called Wesley Dorrian. His cost seems right, though I don’t like the thought of adding a die roll before each shoot. Maybe the controller can choose which bonus applies? (cannons would win out over boarding in most cases, but being able to choose also makes sense thematically based on situational preparation)
Celestial Fire seems overpriced based on how difficult it would be to pull off Repeating Guns – even if you hit every time, you might not need to bother shooting again since 5 hits will take care of most ships. (not to mention the backfiring) I could see her at 16.
Styx is kinda neat; I assume the name is not from the band? XD (any flavor text yet?)
Seems easy to read to me!
