Magic Items

Wondrous item, legendary (requires attunement by a spellcaster)

This ornate chair is designed to propel and maneuver a ship through space.

Passive Properties. The following properties of the helm come into play even when no creature is attuned to it:

When placed aboard a vessel weighing between 1 and 100 tons, the helm generates an envelope of fresh air around the ship while it is in the void of space (but not underwater). This envelope extends out from the edges of the hull in all directions for a distance equal in length to the vessel’s beam, so that creatures aboard and near the ship can breathe normally in space. The temperature within the air envelope is 70 degrees Fahrenheit.
When placed aboard a vessel weighing between 1 and 100 tons, the helm generates an artificial gravity field while the ship is in the void of space, so that creatures can walk on the ship’s decks as they normally would. Creatures and objects that fall overboard bob in a gravity plane that extends out from the main deck for a distance equal in length to the vessel’s beam.
Active Properties. The sensation of being attuned to the helm is akin to being immersed in warm water. While attuned to the helm, you gain the following abilities while you sit in it:

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 or space at a maximum speed in miles per hour equal to your highest-level unexpended spell slot × 10.
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. While attuned to the helm, you cannot expend your own spell slots.

Wondrous item, very rare (requires attunement) This "helm" is a really a projection of light cast by a group of incoporeal fireflies. Fireflies serve instead of gems, vanishing forever once they've done their duty. This dazzling helm is set with 8 diamonds, 12 rubies, 18 fire opals, and 30 opals. Any gem pried from the helm crumbles to dust. When all the gems are removed or destroyed, the helm loses its magic. You gain the following benefits while wearing it: You can use an action to cast one of the following spells (save DC 18), using one of the helm's gems of the specified type as a component: daylight (opal), fireball (fire opal), prismatic spray (diamond), or wall of fire (ruby). The gem is destroyed when the spell is cast and disappears from the helm. As long as it has at least one diamond, the helm emits dim light in a 30-foot radius when at least one undead is within that area. Any undead that starts its turn in that area takes 1d6 radiant damage. As long as the helm has at least one ruby, you have resistance to fire damage. Helm of Brilliance, cont'd (curse you, character limits!) As long as the helm has at least one fire opal, you can use an action and speak a command word to cause one weapon you are holding to burst into flames. The flames emit bright light in a 10-foot radius and dim light for an additional 10 feet. The flames are harmless to you and the weapon. When you hit with an attack using the blazing weapon, the target takes an extra 1d6 fire damage. The flames last until you use a bonus action to speak the command word again or until you drop or stow the weapon. Roll a d20 if you are wearing the helm and take fire damage as a result of failing a saving throw against a spell. On a roll of 1, the helm emits beams of light from its remaining gems. Each creature within 60 feet of the helm other than you must succeed on a DC 17 Dexterity saving throw or be struck by a beam, taking radiant damage equal to the number of gems in the helm. The helm and its gems are then destroyed.

This plate is made of obsidian and so black it seems to be sucking light in from the surroundings

Wondrous Item, Common
This Pole is made of duskwood has descending winged serpents carved.

While holding this 10-foot pole, you can use an action to speak a command word and cause it to collapse into a 1-foot-long rod, for ease of storage. The pole's weight doesn't change. You can use an action to speak a different command word and cause the rod to revert to a pole; however, the rod will elongate only as far as the surrounding space allows.
