Excitement Rush (5e Feat)
From D&D Wiki
Each time you achieve success on some task, a wave of excitement flows through your body. You gain the following benefits:
- When you reduce a creature to 0 hit points, you can use your reaction to make one additional attack against another creature within your range. This attack is made with advantage.
- Whenever you score a critical hit on an attack during combat, you can move up to 30 feet as part of the same action. This movement doesn't provoke opportunity attacks.
- Whenever you go first on the initiative count, you can make one additional attack using your bonus action.
