My take on 3e helms

Just tossing this out for the list to disect:

Spelljamming Helm



A Spelljamming Helm is a device that moves a special ship called a
Spelljammer.  It appears as a large ship's wheel attached to a semi-circular
pedestal.  The pedestal has numerous dials, levers, and buttons.  The
operator of a Spelljamming Helm is called a helmsman.  To qualify to use a
Spelljamming Helm, the helmsman must have 2 ranks in the skill Knowledge
(Spelljamming) or make a successful Use Magic Device skill check (DR 15).



Once activated, it will move a ship in a straight line at a constant speed
until a helmsman commands it to change its course or speed.  To give the
Helm a command, the helmsman needs to make a concentration check (DR 10),
modified by the size of the ship and the maneuver being attempted.  Each
command takes 1 full round and the helmsman cannot take any other actions.
If a helmsman so wishes, he could Take 20 when using a Spelljamming Helm.
If at any point a check fails, the helmsman cannot execute that maneuver and
the Spelljammer continues forward at the speed it was traveling at on the
previous round.



The modifiers to the Difficulty Rating of a command are based on the size of
the Spelljammer and the maneuver being attempted.  Size modifiers are as
follows: Huge (+2), Gargantuan (+4), and Colossal (+8).  If the helmsman is
attempting to change the direction of the ship, the modifiers are: 45-degree
turn (+2), 90-degree turn (+4), 135-degree turn (+8), and 180-degree turn
(+16).  For every 10' of movement that the Spelljammer is moving at, add +1
to the total Difficulty Rating.  These modifiers stack, so for example, a
helmsman that attempts a 90-degree turn in a Colossal Spelljammer moving at
80' per round has to make a concentration check against DR 30 (+8 for size,
+4 for degree of turn, and +8 for the Spelljammer's speed).



A Spelljammer Helm can move ships ranging from Huge (at least 16' long) to
Colossal (at most 120' long).



Cost & means of making?






Look for my coming on the seventh month of the fifth year.  At dawn look to
the world were the Trio (plus one) that is Untouchable reigns supreme
