Wondrous item, legendary (requires attunement by a spellcaster)

The function of this ornate chair is to propel and maneuver a ship on which it has been installed through space and air. It can also propel and maneuver a ship on water or underwater, provided the ship is built for such travel.

Provided the vessel weighs between 1 and 100 tons it grants the ship the following properties.

While attuned to a spelljamming helm and sitting in it, you gain the following abilities for as long as you maintain concentration (as if concentrating on a spell):

<aside> 💡 The sensation of being attuned to a spelljamming helm is akin to the pins-and-needles effect one experiences after one's arm or leg falls asleep, but not as painful

</aside>

• You can use the helm to propel the vessel across or through water and other liquids at a maximum speed in miles per hour equal to your highest-level unexpended spell slot.
• You can use the helm to propel the vessel through air at a maximum speed in miles per hour equal to your highest-level unexpended spell slot × 10.
• You can use the helm to propel the vessel through space at a maximum speed in miles per hour equal to your highest-level unexpended spell slot × 100.
• When engaged at tactical speeds your vessel can move at it’s typical speed +10ft per unexpended spell slot
• You can use the spelljamming helm to move the ship through space, air, or water up to the ship's speed. If the ship is in space and no other objects weighing 1 ton or more are within 1 mile of it, you can use the spelljamming helm to move the vessel fast enough to travel 100 million miles in 24 hours.
• Provided you have at least one unexpended spell slot, you can steer the vessel, albeit in a somewhat clumsy fashion, in much the same way that oars or a rudder can maneuver a seafaring ship.
• Whenever you like, you can see what's happening on and around the vessel as though you were standing in a location of your choice aboard it.

Drawback.
