Improvised Weapon Master, Variant (5e Feat)
From D&D Wiki
Improvised Weapon Master
You are a master at weaponizing anything and everything.
- When wielding an improvised weapon, its damage becomes 1d6 rather than 1d4.
- You also add half your proficiency bonus to attack and damage rolls made with improvised weapons, rounded down.
- After rolling for initiative, you make your first attack with an improvised weapon at advantage. You do not gain this benefit again until you take a short or long rest.
