Distracting (5e Feat)
From D&D Wiki
You are extremely distracting when you want to be, gaining the following benefits:
- When you make a melee weapon attack against a creature, you can use your reaction to cause the target to provoke an opportunity attack, with disadvantage, from another creature of your choice within 5 feet of it.
- When a creature you can see within 60 feet of you that can see or hear you makes an ability check, you can use your reaction to impose a -1 penalty on the check.
