Perfect Striker (5e Feat)
From D&D Wiki
- When you roll a 1 or 2 on the d20 for a melee weapon attack, you can reroll the die and must use the new roll.
- As a bonus action, you may hone your focus and ignore everything around you for a short period of time. When you hone your focus, the first melee weapon attack you make this turn is made at advantage. Once you use this feature, you can not use it again until you finish a short or long rest.
