*POUND* *HAMMER* *BANG*
There, got the bugs worked out. Yes, it's me. The guy who folds, spindles and mutilates one system to make it compatible with another simply because I like the source material.
VIOLA!!!
Spelljammer Helm
SU Cost: 2 x Size + 5 for a basic helm; 3 x Size +10 for an advanced helm.
Power Cost: 1 for every .2 warp, + 1 point of stun damage to the pilot per hour for a basic helm; 1 for every .3 warp, +1 point of stun damage to the pilot per hour for an advanced helm.
This alternate mode of superluminal travel was first developed by the (fill in the name of your uberpsionic race). It consists primarily of a helm called, ironically enough, a helm. The pilot sits in this seat and immediately becomes one with the ship (see Neurogenic Interface). Also, the helm acts as a warp engine/nacelle.
Basic helms grant a maximum warp speed of (PSI + Focus)/2 + System Operation (helm)/10. Pushing this maximum speed takes 3 power and 2 points of lethal damage per hour for each additional +.1 warp up to a maximum of warp 6 or PSI+Focus, whivhever is lower.
Advanced helms grant a maximum warp speed of PSI + Focus + System Operation (helm)/2. Pushing this takes an addition 3 power and 2 points of lethal damage per hour for each additional +.2 warp up to a maximum of warp 9.99 or twice PSI+Focus, whichever is lower.
"But wait," you say. "How does one power such a device since warp drive is powered by the warp engines?"
"Simple," I reply. "Today, we offer for the low low price, our very own, PSI crystals."
PSI Crystals (unless someone can think of a better name.)
SU Cost: 3 x Size
Power Cost: .1 per psionic on board.
The crystals aren't grouped in a single location, rather they form a lattice work throughout the hull. Anyone within the ship who has any level of psionic potential, aids in producing power.
Very simply, the crystals convert latent psionic potential into energy. The crystal produces power by taking one tenth the total psionic potential + focus scores on board the vessel. Some particularly weak individuals will grant a net bonus of nothing as they produce as much as the crystals require to perform the siphoning.
Any non PSI on board must make a standard difficulty test against Resistance (I know it's a specialty, but I don't remember which skill), or fall unconscious until removed from the ship. If successful, all other rolls (except to resist this effect) is at +2 difficulty.
These are submitted for your perusal and open to some light criticism. I am currently at work and just thought this up on the fly (but it took me an hour and 15 minutes to write between calls).
