The Aleksander serves as a calldown for Alexei Stukov in Co-op Missions, appearing as an infested battlecruiser. It launches infested terran bombs as its anti-ground attack, and will attack air units with tentacles that do damage over time. At level 15 these tentacles can mind control air units with its attacks. The Aleksander also crashes when its life times out or it is destroyed, dealing damage to units underneath it and spawning infested terrans for a time.
When the Aleksander is destroyed or runs out of time, it crashes onto enemy units and structures underneath it, dealing 500 damage to all units and structures caught in the crash. It then becomes a structure with no visible hit point bar for 30 seconds. During this time period, it produces infested civilians and infested troopers at a high rate (one infested per second). These units have shortened timed lives (each spawned infested can fight for 8 seconds).
Volatile Infested Spawn Chance Mastery: The crashed Aleksander can spawn volatile infested with a chance to +0.5% per mastery point.
Mastery: +0.5% volatile infested chance per Volatile Infested Spawn Chance mastery point. Up to a maximum 15% chance.
