Necromancer

The Necromancer is a tier 4 tank that upgrades from the Underseer at level 45.

Design
The Necromancer has a square body with four trapezoid sunchip spawners on its edges, which is just bigger comparing to its body than the summoner.

Technical
The Necromancer is a Sunchip tank, meaning it controls squares, or sunchips, instead of shooting bullets. These are controlled very similarly to drones. Sunchips are much weaker than regular drones, but the Necromancer makes up for it in quantity.

The Necromancer is able to infect squares and turn them into sunchips by touching one with a sunchip. If the Necromancer already has the maximum number of drones, the square will take damage instead.

The Necromancer's max drone count is dependent on Respawn Rate (reload) stat, gaining 2 more drones per upgrade.

Upgrades
The Necromancer upgrades from the Underseer at level 45.

The Necromancer can upgrade into the following at level 60:

As the Necromancer

 * Follow the same strategies as with the Underseer; keep your drone count high.
 * Try to avoid bullet spammers, as they can destroy your drones quickly.

Against the Necromancer

 * Use bullet spammers like Twisted Hybrid, Hexa Blaster, and Octo Machine. Use your heavy bullet defense to destroy all necromancer drones, then approach the Necromancer and kill it.
 * Another strategy is to use long-lance classes like Bite of '87, Broadsword, and the Flail class. Approach the necromancer. As the necromancer directs its sunchips at you, retreat while waving your lance to destroy the sunchips. Rinse and repeat until you kill the necromancer.
 * You can also use Propeller-class tanks. Note that you have to be faster than the drones for this to work, and you need to be bullet class. Fire at the drones, and when the Necromancer sends them at you, run away. Continue until the necromancer dies.
