Golem

Golems are constructed creatures, built to carry out a certain purpose intended by their creators. They are often used as guards.

Description
To make a golem, the creature must sculpt them from a given material - typically clay, flesh, iron, or stone though other metals are at times used. They then must infuse it with an elemental "spark of life", an arcane core that "runs the numerous runic details" to animate the golem. Once animated, the golem will follow the commands of the creator. Alternately, during creation, the creator can make an item tied to the golem that permits the bearer to give commands, rather than the creator.

All golems share the following traits: no need for food or sleep; immunity to charm, exhaustion, fear, paralysis, petrification, and poison; immunity to attacks nonmagical weapons not created out of adamantine; immunity to poison damage and to any effects that would change its form; and resistance to magical effects. All but flesh golems are additionally immune to psychic damage. Attacks from a golem, typically made without weapons with the exception of iron golems, are themselves considered magical.

Clay golem
Clay golems are large and have a misproportioned humanoid shape. They are immune to acid damage, and indeed are bolstered by acid attacks. When seriously injured, they are liable to attack indiscriminately until destroyed or healed.

Flesh golems are about the size of a human, but are made from pieced-together body parts. It is slightly more intelligent than other golems, capable of responding to simple reasoning from its creator. They are immune to lightning damage and heal when struck by lightning instead, but they are afraid of fire. Like clay golems, they can become indiscriminately violent when they are quite injured.

Iron golems are large and heavily armored, and as beings of the forge are immune to any damage from fire, healing instead when hit with it. They can wield a simple weapon, such as a sword, and their breath is poisonous.

Stone golems are nearly immune to the ravages of time, and can indeed slow down those around it. They are often used as guards.

Cobalt golems are mighty armored servitors made by arcanists. Meteorites are the primary sources of raw cobalt ore, smelted by way of ferromagnetic alchemy into finished silver-gray cobalt. The final step is to mold and twist it into armored skin, surrounding the central lodestone that fuels the life of a cobalt golem. Most notably, cobalt golems are utilized by Cobalt Soul library to guard their restricted archives.

Forge guardians are the most gargantuam of their type. They were moulded by the All-Hammer to guard the divine furnaces and hearths that designed the first dwarves. Forge guardians are shaped from marble fused with adamantine and filled lava, floating through their veins. These rare and massive constructs exemplify one of the highest forms of artistry known to Exandria. Together with fearsome fighting skills, the golem is also able to assist a blacksmith creating new golems.

In birth, platinum golems are fused with the spirits of indomitable warriors, fueling them with the need to execute its master's orders to perfection. Temples of the Platinum Dragon craft these golems using divine rituals and imbue them with the unflinching devotion to justice epitomized by their god.

Mage hunter golems were created by gods to manage the arcane ambitions of mortals. They are able to temporarily disrupt magic in certain radius, absorb medium level spells, or collar a mage with its claw, forfeiting their magic abilities.

History
During the Age of Arcanum, mortal races, empowered with gods' arcane gifts, began to experiment with manufacturing "life". The dwarves succeeded first, animating autonomous wardens to protect their domain. However, their knowledge was quickly stolen and scattered throughout Exandria.
