Terra

The spirit of Terra, or Earth, controls the flow of raw inanimate matter within the corporeal plane, bending the world to its will to create or destroy as it sees fit. Terra is the most visible of the spirits, excluding Lumen, for without Lumen, there would be no sight at all. The ground, rocks, metal, armour, a body, everything that can be touched was created by Terra.

Terra controls the strength and density of the material world, and thus invoking it would greatly strengthen your body and aura.
