Acid Spit (Ex)
Each round as a swift action, an amalgamite swarm can emit a stream of acid at one target with a range increment of 10 feet.
Amalgamite swarms are immune to this acid.
As a full-round action, an amalgamite swarm can disperse, spreading itself across a 30-foot cube. While dispersed, it deals no damage and can’t use its other special abilities until it reforms. A dispersed amalgamite swarm can make Stealth checks even without cover or concealment or when being directly observed, and when dispersed it gains a +10 bonus on its Stealth checks and does not take increased damage from area effects as normal for being a swarm. Reforming into its normal swarm form takes 1 minute, and while reforming its bonus on Stealth checks is reduced to +5.
Scuttling Swarm (Ex)
An amalgamite swarm can use its Step Up feat to move and reshape itself when a creature takes a 5-foot step while within the swarm’s area. Each part of the swarm can move 5 feet, provided each part of the swarm ends this movement in a square occupied by the creature taking the 5-foot step or in a square that the swarm occupied before taking this movement.
Movement taken by the swarm when using this feat does not provoke attacks of opportunity.
Environment any land or underground
Organization solitary, pair, or assimilation (3-6)
Originally forged as a self-replicating tool by a now-extinct race of artificers, these tiny animated machines were subverted by the Hegemony, used to destroy their creators, and then utilized as a weapon of conquest. By itself, each individual amalgamite component has sentience but little more.
However, when they bring themselves together to form into insect-like amalgamite units, a hive-like consciousness forms. Amalgamites are inextricably bound to follow their programmed commands but they have the capacity to learn and are often quite cunning in how they follow out their orders.
Amalgamites use their acidic spittle to break down small qualities of common minerals for energy to sustain themselves. They can also rapidly self repair damaged or broken components, but this requires considerably more energy. The process of creating amalgamites is complex and a closely guarded secret, but amalgamites can replicate by themselves. This requires qualities of refined metal imbued with significant amounts of magical energy. Due to the potential danger of amalgamites reproducing out of control and destroying their owner’s valuables, amalgamites routinely have strict safeguards integrated into them that limit the total amount of units in a swarm.
