The Mechadendrite Hive is the name given to a mass of tentacle-like augmetic limbs that can be used for utilitarian -- or more deadly -- tasks. Hissing and slithering like a nest of mechanical snakes, the Mechadendrite Hive employed by some of the most powerful and heavily augmented Tech-priests of the Adeptus Mechanicus engulfs the foe in dozens of steel tendrils. Lashing, stabbing and throttling, the mass of Mechadendrites bloodily disassembles its victims with horrific speed.
