The Spear of Adun (mission)

The Spear of Adun is the third mission of Legacy of the Void.

Background
""The Spear of Adun... I... I am honored to have this opportunity. This is fortune we cannot ignore."

- Karax

Near Khor-shakal, Phasesmith Karax is ambushed by a group of zerg, only to be rescued by Artanis and his forces. Karax tells them that his nerve chord has been cut to remove him from the Kalah. Artanis says that he needs Karax to activate the ancient generators powering the Spear of Adun, so that he can take the last uncorrupted Protoss and retreat from Aiur.

The Mission
""Every hand is turned against you. Even the ground beneath your feet carries the seeds of my victory."

- Amon in Selendis's body

Karax activated one of the generators, only to find the other four were clogged with zerg creep and needed to be cleared out. Amon revealed himself in Selendis's body, telling them that their efforts were hopeless. Each generator was defended by groups of zerg and protoss under Amon's control. As the Daelaam defeated the defenders and activated the generators, Amon would send nydus worms and warp prisms to harass Artanis's Nexus. Hybrid were also fielded, but all of Amon's forces were held back long enough to reactivate the generators

Aftermath
""We will avenge what has transpired Karax. And we will free the Templar!"

- Artanis

The Spear of Adun came online just as Amon sent a large wave of forces to overrun Artanis's base. Artanis had all uncorrupted Protoss aboard, and departed Aiur.

In a moment of peace, Artanis and Karax marveled at the engineering of the massive ship and its many functions, though they mourned the loss of the Kalah. Artanis made a vow to avenge their defeat on Aiur, and free the protoss chained to Amon's will.

Walkthrough
The mission is to clear out the four power generators while defending the main protoss base from constant waves of attackers from both sides. A series of shield batteries and photon cannons can defend each ramp to keep the waves out, but as the game progresses Amon will start sending larger and larger attack forces with hybrid and immortals that quickly destroy cannons. Rebuilding lost structures, and warping in defensive reinforcements will be necessary later in the mission.

Scattered across the map are three warp gates that can be captured to help reinforce faster. Grabbing the first one quickly will gain the player access to transforming gateways into additional warp gates. With each generator destroyed, Amon spawns waves of nydus worms and warp prisms to siege the player's base, and it is recommended that forces be pulled back to destroy them before the main base is overrun.

Through the mission the player is given access to the Spear of Adun's ability to deploy pylons anywhere there is vision. This is useful for setting up frontline pylons near large engagements so that reinforcements can be brought to the front quicker.

The southeastern generator is heavily defended by zerg, protoss and hybrid defenses. If necessary, there is a ramp beneath the easternmost generator that leads to the rear of the last generator. This allows the player to destroy the generator while bypassing most of its defenses.
