How to learn Potent Blood
The following manual supplies the book unlock for ranks marked “Manual unlock” in the rank table. Skill points and time are spent when you purchase the rank. See the skill book guide for manual requirements and planning examples.
Use Potent Blood for a chance to pay no Health
Potent Blood gives Witchcraft Abilities a chance to cost no Health: 20% at rank 1 and 40% at rank 2. This is a chance on a cast, so keep enough Health for casts that still charge their normal cost.
Frugal Witchcraft is the prerequisite. It addresses Health spending through its own cost reduction, while Potent Blood can waive the cost entirely. Potent Blood does not describe an Activation Charge refund; Unholy Fervour is the separate perk to compare for that resource.
Vera and the Matriarch sell the manual. Visit Vera during the day, or reach the Matriarch’s shop peacefully through Song of the Mountain. Both ranks need the manual and cost three skill points and two time segments in total.
