Void Admiral Agrolekh

Background
Agrolekh is the fleet master of Szaregon's army. He is also a destroyer type construct which implies that at some point he was damaged in his slumber or he always was adherent to the nihilistic philosophy of the destroyer. Although the fact that he is already in a destroyer form when he wakes points to the second hypothesis. Agrolekh also commanded Necrontyr troops in the "War in Heaven" which was the conflict that resulted in the Necrontyr to become the Necrons.

Battle Informations / Strategies
Agrolekh is a Necron Destroyer Lord. He is initially fought during the introductory mission, but to defeat him at that stage is not expected of the player, and the goal is to instead escape and return to fight later in a repeat of the fight.

He starts with 40 hp on normal difficulty, and 5 energy armor. Each turn, he changes his armor to 5 physical, and continues in that changing pattern each turn. He can only attack in melee, and thus flanking characters with gun range such a Skitarii Vanguards and Ranger Alphas may be appropriate. His damage is ~6, and will be enough to dispatch servitors with ease, but they may be useful as distractions nonetheless.

One effective strategy is to move up the sides to deal with the warrior spawns, if not ignore them outright as their damage output should be minimal at this point. Next, move one melee unit close enough to the center to draw aggro (reaching the direct middle platform is too far). Use canticles to gain cognition and increase damage or ignore armor as need be. Power Fields to increase physical damage with a Level 2 Vanguard having 2 shots is highly effective at ripping through his health, and with a solid Dominus flanking and Explorator to aid in the center, should only take about 2-3 turns to eliminate him and end the mission.

On the path to the fight, the tactic of staying at a distance being chosen will grant a benefit to initiative.
