Overseer

Description
The Overseer has a uniquely destructive perspective on the world. An energon thruster keeps it buoyant, while its infamous eye, once trained upon its enemy, can fire a refined Optical Laser Burst at its target. Its cache of Memro! powers most of this Thrall's functions.

Attacks / Movement
The only means of attack for these slow-flying machines is their optical lasers. Defensively they can places blocks tactically to hinder movement and barricade breached structures. Block type improves with experience.

Abilities
1 - Force Field: Creates a Force Cube anywhere near the thrall, which grows in strength the higher the Overseer's rank.

2 - Assembler: When energy permits, Overseers possess the ability to generate energy force fields that surround and protect all units within the Thrall's range.

Trivia
The "Force Field" ability is the third way to circumvent the build restriction around the Nexus, after gravestones and Olfrum's mushrooms.
