Large Weapon Master (5e Feat)
From D&D Wiki
Large Weapon Master
When you take this feat, choose one melee weapon. You must be proficient with this weapon, and it cannot have the reach or heavy properties. You can wield a Larger version of this weapon without disadvantage. You cannot use the thrown or finesse property of a larger weapon, but all other properties (versatile, and two-handed) apply as with a regular weapon. You cannot dual wield while using a Large weapon.
Attacking with a Larger weapon requires additional strength beyond a normal weapon. On a turn where you attack with a Large weapon, you cannot use a bonus action to Hide, Disengage, or Dash. You may still use all attacks you get from a normal attack action, as well as any granted by feats and features, such as Hordebreaker.
When using a Larger weapon, you deal 1 additional damage die of the weapon's usual type and you duplicates any damage bonus or ability modifiers to that damage.
You may take this feat multiple times, choosing a different weapon each time. You may also take the same weapon a second time to regain use of your bonus action.
