You magic can be fueled with your own blood, increasing its potency.

Prerequisite(s): 1st-level druid

Benefit: Prior to casting a spell, you may wound yourself to feed the magical energies you unleash. You may suffer 3 points of damage (which cannot be prevented in any way) to generate one of the following effects.

• The target's spell resistance is reduced by two.
• The spell DC is increased by 2.
• The spell deals +1 damage.

You may deal damage to your target in multiples of 3 to generate these effects, up to a number of times equal to 1 + your Constitution bonus (if any).

Special: A spell need not be prepared ahead of time as an empowered blood spell in order to take advantage of this feat.
