Material Studies: Thaumium is a research option found under the Golemancy tab that can be purchased with 3 levels of experience after researching Material Studies: Brass, and allows for Thaumium Golem bodies to be produced.
Although more difficult to obtain, Thaumium is stronger than Iron while being equally as slow. They are also resistant to magic, making them good combat or guardian Golems in areas such as Magic Forests and the Nether, where magical enemies, along with fire and explosions, to which Thaumium Golems hold resistances to, are prevalent.
