Vengeful

You are determined to deliver retribution to those who strike you down. You gain the following benefits:

• When you take damage that causes you to drop to 0 hit points, you may use your reaction to make one melee weapon attack before you fall Unconscious.
• When you roll a 19 or 20 on the d20 for a Death saving throw, you regain 1 hit point. Once you use this benefit, you cannot do so again until you finish a long rest.
• If a creature you can see deals damage to you that reduces you to 0 hit points, you have advantage on the next attack roll you make against that creature. Additionally, the next time that creature sees you move towards it, you can choose to have it make a WIS saving throw contested against your Charisma (Intimidation) check - on a failure, the target is frightened for 1 minute. The target can remake its saving throw at the end of its turn, ending the condition on itself on a success.
