Swordspear (5e Equipment)
From D&D Wiki
Martial Melee Weapons
A swordspear is similar to a normal spear in length, but with a bigger, wider blade that sacrifices the balance of the spear (and hence its ability to be effectively thrown), as well as making it more difficult to wield. A swordspear makes up for its disadvanages with its damage output.
The thick "spear tip" can allow for large, slashing attacks as opposed to the normal piercing strikes of a spear. Prior making an attack on a creature, a swordspear's wielder can choose to deal either piercing or slashing damage against the target. If it is not decided prior to an attack, the damage defaults to piercing damage.
Special. If you are not Small or smaller, you can treat the weapon as a reach weapon. If you do so, you have disadvantage on the attack roll.
