You specialize in the art of disruptive magic. You are especially adept at counterspells and dispelling magic. When you take this feat, you gain the following benefits:

• You learn either the counterspell spell or the dispel magic spell. The spell you pick is always prepared, and it doesn't count against either the number of known spells or the number of prepared spells for you. Use your spellcasting modifier on all rolls made for these spells.
• Whenever you attempt to use counterspell or dispel magic, you have advantage on any roll made to disrupt the spell or magical effect.
