## Arcane Consumption *You can sacrifice your physical health to strengthen a spell. This process leaves you wracked with pain, but the enhanced energy you draw from the spell might provide the margin between victory and defeat.* **Prerequisite:** [[Arcane Toughness]], [[Toughness]], arcane caster level 6th **Benefit:** As a swift action, you can bolster a spell you are about to cast with your own blood. You take 1d6 points of Constitution damage, and your spell's save DC increased by 1 for every 3 points of Constitution damage you take. This process leaves you exhausted for 1 hour. You cannot gain the benefit of this feat if you are immune to Constitution damage.
