Infused with Power. The Gaze has been anointed with the Gift of Battle from a Banner of the Krig Rune, a Spelljamming Helm, and a Battle Standard of Infernal Power next to the helm.  

While in the 500-foot-radius sphere centered on the deck, the crewmates are immune to the frightened condition and gain a +1 bonus to attack rolls and AC. Additionally, while a creature is attuned to the standard and holding it, any weapon attacks of all allied creatures within 300 feet of them count as magical for the purposes of overcoming damage immunities and resistances.

Dread Necromancy. Any undead crew under the control of a captain of the ship can be commanded with a free action instead of a bonus action, if they require one to command.

Spelljamming Helm. 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):

• 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.
• You can steer the vessel, albeit in a somewhat clumsy fashion, in much the way that a rudder or oars can be used to maneuver a seafaring ship.
• At any time, you can see and hear what’s happening on and around the vessel as though you were standing in a location of your choice aboard it.

Transfer Attunement. You can use an action to touch a willing spellcaster. That creature attunes to the spelljamming helm immediately, and your attunement to it ends.

On its turn, the Gaze can take 2 actions, choosing from the options below. It can take only 1 action if it has only one crew. It can't take these actions if it has no crew.

 Move. The Gaze can use its helm to move with its sails or by use of the spelljamming helm. It can move up to the speed of one of the ship's movement components, with one 90-degree turn.

Fire Cannon. Ranged Weapon Attack: +7 to hit, range 600/1200 ft., 1 target. Hit: 44 (8d10) [bludgeoning] damage.

 Breath of Fear. (1/day) - A creature attuned to the spelljamming helm can telepathically command the boat to emit a green fog from the boned figurehead adorning the front of the Undying Gaze. Each creature in a 30-foot cone must succeed on a Wisdom saving throw (DC 15) or drop whatever it is holding and become frightened for one minute. If the creature ends its turn in a location where it doesn’t have line of sight to you, the creature can make a Wisdom saving throw. On a successful save, the effect ends for that creature.

A cannon is usually supported in a wooden frame with wheels. Before it can be fired, the cannon must be loaded and aimed. It takes one action to load the cannon, one action to aim it, and one action to fire it.
