Sadist

You delight in the suffering of others and strike your enemy in ways to maximize their pain.

• Before you make an attack on a creature where you may add your proficiency bonus, you can choose to take a -5 penalty to the attack roll. If the attack hits, the target becomes frightened of you for 1 minute due to the intense pain of wound. The target makes a Constitution saving throw at the end of its turn to end the effect (DC is 8 + proficiency bonus + modifier used for attack). Once a target saves against this effect, it is immune to this ability for 1 hour.
• You gain proficiency in the Intimidation skill.
