Two Weapon Slayer
Prerequisites: The Two-Weapon Fighting fighting style.
You've learned how to master the arts of dual-wielding. Due to your mastery in this field, you gain the following benefits.
- When you engage in two-weapon fighting and you hit at least once with both weapons, you deal an extra 1d4 damage on your last hit.
- When you reduce an opponent to 0 hit points while dual-wielding, you may make two weapon attacks using your bonus action instead of one.
