Complex Number

The  is a tier 5 tank that upgrades from Fractionalizer at level 60.

Design
The has a design very similar to the Fractionalizer, with the exception of the color of the barrels, which are green and purple rather than black and white, respectively. Compared to Fractionalizer it also gains a dot atop its body, colored the same green as its barrel.

Technical
As indicated by the dot, this tank's green drones have the special alt-ability.

The green drones (fired from the green barrel) on shift or right click (aka alt-fire) are turned into Reinforcements portals. As expected, each of these portals is intangible until it naturally expires, where it then releases 4 AI controlled swarm drones. The purple drones function as normal drones.

Trivia

 * In mathematics, a complex number is the sum of a real number and an imaginary number, such as (3i + 2) where i is the imaginary value.
