Can a Mithral Great Sword be used as a Kensei Monk's Kensei Weapon?
If Mithral is a light weight material for armor....can it work with weapons? Meaning would a mithral great sword negate the heavy property?
Kensei Weapons. Choose two types of weapons to be your kensei weapons: one melee weapon and one ranged weapon. Each of these weapons can be any simple or martial weapon that lacks the heavy and special properties. The longbow is also a valid choice. You gain proficiency with these weapons if you don't already have it. Weapons of the chosen types are monk weapons for you. Many of this tradition's features work only with your kensei weapons. When you reach 6th, 11th, and 17th level in this class, you can choose another type of weapon—either melee or ranged—to be a kensei weapon for you, following the criteria above.
