[3.5] (Spelljammer) Sharkentine Empire Troops. (Please Critique)

[Pika...]

Hi, could use some advice on this race. The first I have made as a Homebrew meant to be a big reoccurring enemy race (Thing Wraith or Jaffa) along with their will-broken slave race the Crucians (Official D&D race).


Some info on this Speljammer race:
1. They are from a cluster of solar system spheres (think my version of a "galaxy" in the Material Plane/Spelljammer Plane) which is on the far/outer reaches of unknown space.
2. There they have not met a race able to take them, and their limited Spelljamming abilities, on. They have conquered most of their cluster with only a few worlds/spheres remaining free.
3. There are no standard races, nor any of the main spelljammer influences in this sphere minus the Neogi who act in secret supplying the Sharkentine Empire with it's only method of Spelljamming: Lifejammers (aka Helms that drain life from a pilot/victim/slave for power).
4. Mechanically they are meant to function in "squads". Normally four Sharkentine Empire Basic Warriors (1) led by a Sharkentine Empire Squad Leader.
5. Squad of higher armored slaves are also used in the form of four Crucian warriors led by a single Sharkentine Empire Basic Warrior (1).
6. The reason I did not armor the Sharkentines is because they are an aquatic race, so metal is out, and since they have +4 natural and are so deadly in combat no race in their native cluster of spheres have been able to take them on so they see no need for improving their gear in the moment.
7. I am running an E6 game, so they will be used extensively for a while without becoming "weaker" by usual D&D terms.
8. They only use (or possibly know how to make) Turtle Ships (aka "Battle Boats"), especially since turtles are kinda numerous here...
9. Now that these strange alien PCs are here from some unknown spheres they Sharkentine Empire is VERY eager to interrogate them. And then maybe see what they taste like in clam soup.
10. Their "Water Tanks" provide 12 hours of Clean Breathable Water, and four hours of Fouled Water. (As the mechanics for Fouled Air in Spelljammer)

Used as both troops, and "food" for their Lifejammers.





So, thoughts on these guys? Any changes you can suggest? Improvements? Likes or dislikes about them?

Many Pikas in advance!
