Wands with dragon heartstring cores are powerful and capable of flamboyant spells. They learn quickly but are somewhat fickle, and their allegiance is easily swayed from one owner to another. They favour strong owners and are sometimes temperamental, though never lacking in raw magical strength. While they can be turned towards dark magic more readily than unicorn hair, they are not inherently disposed to it. These wands are prone to accidents, but in skilled hands they deliver extraordinary results.

Approximately 9.00% of witches and wizards have this type of wand core.
