Material Transmutation

All Qút̤a have the magical ability of Material Transmutation. Material Transmutation is the ability to expend Mana to transform one material into another.

Capacity
Capacity is the maximum amount of Mana a Qút̤a has. About 25% of inhabitants have a Capacity below 100,000, and about 50% of inhabitants have a Capacity below 300,000. A Qút̤a is always consciously aware of their current Mana level. They instinctively know how much Mana transmuting a material would cost, although they do not know individual values, such as the density, atomic number, and atomic mass. All Qút̤a have a set Max Purity at birth, as well has some sort of Capacity. A Qút̤a's expended Mana resets once a continuous rest of 10 hours is taken, called Mana Restoration.

Mana Exhaustion
As more Mana is used, symptoms of Mana Exhaustion begin to take effect and worsen as more mana is expended. Mana Exhaustion is caused by a buildup of oxygen in the Mana Pathways. This on its own only causes mild symptoms, but the oxygen in the Mana Pathways begin to diffuse into the body and surrounding blood vessels, causing Hyperoxia-like symptoms.
