Arcane Consumption

You can empower your spells by pouring your own life force into them.

Prerequisites: Constitution 13, Endurance

Benefit: You can render yourself fatigued to increase the DC of a spell you are casting by 2. If you use this ability while fatigued, you become exhausted. If you use this ability while exhausted, you fall unconscious.

You may not apply multiple levels of exhaustion when casting one spell.

If you are immune to exhaustion, you can’t gain the benefit.
