Golems are magical constructs made of inert matter animated by powerful Arcanists through the use of spells during magical rituals. The main aspect differentiating one type of golem from another is the material from which it is built. There are four standard types of golems, from weakest to strongest: flesh golems, clay golems, stone golems and iron golems. The flesh golem is created from human remains, and the others are created from earthen components: clay, stone and iron respectively. Virtually any material can be used to create a golem, and hundreds of different types of such creatures have been described but all are based off one of the 4 main arch types.
