Spear of Adun

"The Spear of Adun. A marvel of Khalai engineering, and last of the three great arkships. Each created to ensure the continuation of our culture in a dark time."

- Phasesmith Karax

The Spear of Adun is an arkship, and the flagship of Hierarch Artanis in the war against Amon.

Overview
The Spear is a large ship, able to carry an entire protoss civilization. It is equipped to field armies of zealots, and can even store fleets of carriers and motherships within its hangars. While ancient, its technology is still advanced by the current standards of the protoss. Such is its level of firepower that it could singlehandedly wage a war by itself.

The Spear possesses the ability to destroy entire planets, along with cloaking technology.

Origins
"A hidden flaw brought down something mighty. You want to find a solution to all hidden flaws."

- Orlana

The Spear was created long prior to the Great War, along with two other arkships following the suggestion of the three Grand Preservers, Shantira, Orlana and Rohana. This was done to ensure that the protoss would have the means to preserve their civilization in the event of said civilization being placed in jeopardy. Templar Caste warriors voluntarily entered stasis onboard the vessel, giving the protoss a slumbering army that could be called upon if needed.

It should be noted though, that the Spear of Adun, together with the Pride of Altaris and the Memory of Nezin, was not built to be merely another weapon of war to be thrown at the first foe, but it was to be preserved until the looming extinction. In fact it would have been wasted if it had been used to forestall survivable tragedies.

The Call to War
"With this vessel, we will avenge what has transpired, Karax. And we will free the Templar."

- Artanis

The Spear had lain dormant for centuries prior to being re-purposed by the Protoss Protectorate. Work had to be done to get its systems back online. It was present at Aiur when the Golden Armada launched its attempt to retake the planet, but was forced to flee when Amon sent the protoss forces into retreat.

Korhal
The Spear traveled to Korhal, which was under attack by the Shadow Corps. The ship provided support for the defenders on Sky Shield.

Bridge
The bridge is the helm of the ship.

Orbital Assimilator
The Spear is equipped with an orbital assimilator.

Solar Core
The solar core is manned by Karax.

Star Forge
A star forge is located in the ship's lower decks. It is capable of constructing weapons of war.

War Council
The war council is manned by Rohana.

Game Unit
"With the touch of a button, you can command that arkship to destroy an entire enemy army. And you’re gonna need that fire power, ’cause the threat of the Xel’Naga is very real."

- Dustin Browder

Legacy of the Void
The Spear of Adun is the hub of StarCraft II: Legacy of the Void, similar to the Hyperion and leviathan of previous games. It can be upgraded through solarite, which grants it abilities that the player can use in missions. The ship's abilities are sorted into 6 columns, along with auxiliary systems. The higher an ability is in a column, the more powerful it is. Each column is moved through sequentially. Not every ability can be used in a single playthrough, even with a 100% completion rate of objectives. In a mission, the abilities are listed in icon form in the top of the screen. The Spear has a maximum of 200 energy, and some abilities.

As the player collects solarite for completing optional objectives, the Spear's power output rises and the player can activate more abilities at a time. Solarite not being used to activate abilities can be diverted to the auxiliary systems, which are divided into three categories: raising the regen rate of shields, lowering construction rate of buildings, and raising the initial supply the player has on each mission. Every five units of solarite diverted to one of these auxiliary systems gives a 5% bonus to it, to a maximum of 20% with twenty solarite allocated.

The Spear of Adun's abilities are sorted as follows:

Tier 1
All Tier 1 abilities cost 75 energy to cast and have a 60 second cooldown. From left to right, each ability requires an allocation of an additional 25 solarite to unlock.

Tier 2
All Tier 2 abilities cost 50 energy to cast and have a 60 second cooldown. From left to right, each ability requires an allocation of an additional 25 solarite to unlock.

Tier 3
All Tier 3 abilities are passive effects that always take effect when appropriate. From left to right, each ability requires an allocation of an additional 25 solarite to unlock.

Tier 4
All Tier 4 abilities start on cooldown, and have varying energy costs and cooldown. From left to right, each ability requires an allocation of an additional 50 solarite to unlock.

Tier 5
All Tier 5 abilities are passive abilities. From left to right, each ability requires an allocation of an additional 50 solarite to unlock.

Tier 6
All Tier 6 abilities cost no energy and start on cooldown. From left to right, each ability requires an allocation of an additional 50 solarite to unlock.

Allied Commanders
The Spear is accessible to Vorazun and Artanis in Allied Commanders, allowing them to use various abilities in relation to it.

Heroes of the Storm
"Yes, my starship follows me wherever I go. It is like what you terrans call a pet. Only useful."

- Artanis gets snarky

The Spear provides support powers for Artanis in Heroes of the Storm.

Trivia

 * When designing the ship, Blizzard went for something that was "very high concept, and very protoss." However, due to its long history, the design had to incorporate archaic designs that would blend in with modern protoss ones. Thematically it represents the idea of the protoss clinging to the past, standing as a contrast to what their civilization is now, as opposed to what it once was.


 * As part of its 2015 April Fool's event, Blizzard advertised a Spear of Adun replica (estimated completion date 2315), and one to scale. This included a link to its merchandise page with a special price of $9,999,998.00 (a whole $1 discount).


 * A Spear of Adun portrait will be available to players who attend BlizzCon 2015 or purchase a virtual ticket for the event.


 * The Spear is 224 times larger than a Nimitz-class aircraft carrier. Through the comparison, its length, width, and height, can be roughly ascertained.
