Spellbreaker (5e Feat)
From D&D Wiki
Prerequisites: The ability to cast at least one 3rd level spell
You have learned how to more easily disrupt magic through arcane means, gaining the following benefits:
Your rolls made to counter or dispel spells or other magical effects or other similar magic are made with advantage.
You learn the spell Dispel Magic if you don’t already know it. You can cast it once without using a spell slot. You can't do so again until you finish a long rest.
When you cast a spell with the casting time of 1 action to end a spell or other magical effect you may instead cast it as a bonus action. You may use this ability an amount of times equal to half of your proficiency bonus (rounded down). You regain all uses of this ability after a long rest.
