A teaser from the next chapter: Alter Program.
This Matter Arcanum spell combines two materials on multiple dimensions depending on the caster’s intent.
For example, a mage has cast Alter Program and combined a gun with a stick of dynamite to create a compact grenade launcher of sorts. A mage of the Matter Arcanum can combine copper with rubber to create a rubber elastic yet conductible material. In essence, they can combine nearly any mechanism or material trait with another object.
