Iaijutsu Master (5e Feat)
From D&D Wiki
You have mastered the art of attacking as you draw your weapon, granting you the following benefits:
- You may add half your proficiency bonus (rounded down) to your initiative rolls in combat.
- If you attack a creature in the same turn that you draw your weapon, you may add your Dexterity modifier to attack and damage rolls made against that creature this round. You must have higher initiative than the creature you are attacking for this bonus to apply.
- As part of a bonus action with a slashing weapon, you may choose to sheathe that weapon immediately after attacking.
- If your weapon is sheathed, you may use it as an improvised weapon during an attack of opportunity. You gain proficiency with sheathed weapons as an improvised weapon.
