Fanon:Master

The Master is one of the many upgrades of the Overseer at level 45. It does not upgrade further. Idea by Diepmon.

Design
It is a circle with 3 drone spawners evenly spaced at 120-degree increments, exactly like the first design of the now-removed Master.

Technical
It combines all the drones of the Overseer branch (excluding those of the Battleship) all into one: One spawner spawns up to 6 controllable triangle drones, the next spawner can summon up to 4 tank minions, and the last spawner is a Necromancer spawner that allows you to control up to 5 base drones. With the last one, reload still functions as normal but now the upgrade button reads "Reload/Drone Count". Each upgrade point of reload allows for an additional drone, so there can be a max of 12 drones.

With so many kinds of controllable ammunition, this tank may seem overpowered, but there's a catch: only one type of drone can be manually controlled at one time. However, the drones that you aren't controlling don't disappear all of a sudden. They just hang around like normal drones and auto-attack things nearby. If those uncontrolled drones are destroyed, however, the spawners will not fire out new ones until you are controlling that drone group.

To clarify, here's an example: You are controlling your triangle drones. The tank minions and square drones spin around. A Twin comes and blasts away one tank minion, two square drones, and one triangle drone before you maul it. That one triangle drone will be fired out again by that specific spawner, but the tank minion will not be reloaded until you swap over to that drone set. In addition, you cannot just bump into squares while you are still controlling your triangle drones just to get square drones. It doesn't work that way. You have to be in that specific drone set to capture squares with your drones or your body. To swap to a different drone set, press G. A notification will appear telling you which drone set you have swapped to.

Trivia

 * Based on the very first vanilla Master design, but remastered (not intended) with an all-new unique mechanic.
