Antikytheres [New Clockwork Monster]

During the best.monster.ever discussion there was a request for clockwork horrors. Here's my version of the, sort of the fantasy version of self-replicating machines that just don't know when to stop.

ANTIKYTHERES

Antikytheres are clockwork creations of magic-users designed to retrieve rare earths, metals or gemstones for their alchemical work. They look like scarabs fashioned from precious metals and their dim programming sometimes blossoms into true intelligence, allowing them to reproduce and form hordes. These hordes can descend on a region and strip it bare of mineral resources, all for the purpose of making additional antikytheres. It is not for nothing that dwarves and gnomes attack them on site and then pursue their creator with a rare determination.

Antikytheres are small creatures that look like scarabs with six jointed legs ending in spikes, mandibles capable of chewing through stone and wing flaps that can open to release razor-sharp chakrams. An antikythere holds six of these missiles.

The bronze antikytheres are the basic models. Silver antikytheres are more intelligent than bronze antikytheres and are also immune to acids. Through a nozzle in their mouths they can spit acid once every three rounds. The acid emerges in a 10-ft line and otherwise conforms to the acid arrow spell. Gold antikytheres are the most intelligent form of the construct. They are also immune to fire and, in instead of spitting acid every three rounds can spray a 15-ft. cone of alchemist’s fire once per day.

Although terrifying enough alone, when five antikytheres work together they can set up vibrations that can cause a small earthquake (per the spell). Each round, there is a 5% chance per antikythere involved (remember, there must be at least five) of causing the earthquake effect. Other antikythere in the area of effect have a +3 bonus to save vs. the earthquake due to their knowledge of it coming and their ability to clamp their spiked legs into the ground for stability.
