Burning Blood

Inflicts damage on a target over time rather than in a single hit. No duration or damage figure is published. The walkthrough describes what it actually does: it boils the target's blood and burns the skin, dealing physical damage over time, and it briefly staggers them on application. That stagger is the part that matters for sequencing — it buys the opening, and the burn collects the rest while Coen is doing something else. Like every hex it is paid for out of Coen's own health, which is what Frugal Witchcraft exists to soften.
