One of the things that needed refinement in the AC boxed set was "fightable" villans. The neogi were within range of the average player character parties, and could be adjusted to suit the DM's needs. The Illithids were another problem. Mind-flayers are very powerful creatures (even if you use the magic-like version in the MC, for those of you who do not want deal with Psionics in Spelljammer) and a Nautiloid is an extreamly dangerous ship to get near. I resolved that by having the illithids also use Squidships and Lamprays as their "light" cruisers and scouts. Most ships contain only one to four illithids with the balance being Varan henchmen. This will bring encounters down to survivable levels should the players deside to not use negotionation and attack (a foolish endevor indeed).
The Antilians present a different problem with their huge Crystal Ships (dreadnaught class in my opinion). Dreadnaught are usually expensive to build and maintain, so I created a less formitable and expensive ship for the Antilians to rely upon (and players to encounter/fight): the Antilan Warbird.
I used the cardstock picture and deckplan of the Light Heldannic Warbird from the Champions of Mystara boxed set (I believe it also appeared in an issue of the Dragon; Heroes of the Princess Ark series), but gave it the following stats:
[ Note: The deckplans are the same as for the Taripor Warbird. --ed ]
No major changes need to be made to the deckplan key since it already had a helm room and weapons locations. I assigned a standard crew of the following Antilans:
Note: After an encounter or two, players should learn to recognize the rank of an Antilan crewman by the markings/style of their masks.
Still a deadly challenge, but a little more managable for higher level characters (This is intended for a role-playing encounter such as a boarding to search for escaped slaves or suspected Illithid spies.) These ships are also encountered outside the Antilan Empirer (which is near the sun), since they are not dependent on the Firefall's rays to increase its power.
