@ErosRising Most reach weapons two-handed martial weapons which are just reskins of the following:
>Glaive
>Martial Weapon, Melee Weapon, None
> 20gp, 6 lbs. 1d10 slashing - heavy, reach, two-handed
> Heavy. Small creatures have disadvantage on attack rolls with heavy weapons. A heavy weapon's size and bulk make it too large for a Small creature to use effectively.
>Reach. This weapon adds 5 feet to your reach when you attack with it. This property also determines your reach for opportunity attacks with a reach weapon.
