Phoenix tail feather is a popular wand core due to its versatility and power. Its main strength lies in Defense Against the Dark Arts, although its adaptability can wrench it to hexes and jinxes if need be. As with the dragon heartstring core, the phoenix core is common amongst Light Wizards, but its users are not necessarily Light Wizards. This core may specifically impede Dark spells, so it is not common amongst Slytherins. However, it is by far the most common Gryffindor wand core, and is not unusual amongst Ravenclaws and Hufflepuffs.
