Porcupine quills are the sharp spines that cover porcupines, defending them from predators. Porcupine quills are plentiful since the animals continually replenish them.
Porcupine quills are an ingredient in several potions, either whole or powdered, including the Cure for Boils and Elixir to Induce Euphoria. Quills that cause no harm are considered the best by potion-makers.
