Mandible Bident

This chitinous, two-pronged weapon still shudders with predatory instinct, magically biting down on creatures it hits. Once on each of your turns when you hit a Medium or smaller creature with this magic bident with a melee attack, you can force that creature to make a DC 13 Strength or Dexterity saving throw (its choice). On a failed save, the creature is grappled by you and is held in place by the weapon. A creature can use its action to make a DC 13 Strength check, freeing itself or another creature within its reach from this grapple on a success. You can't use the weapon to attack another target while it's grappling a creature in this way, but you can choose to deal 1d8 bludgeoning damage to the grappled creature automatically in place of any attack you'd make with it as part of the Attack action, as the weapon's pincers clamp down tightly around the target. You can release a creature from the bident's grapple on your turn (no action required). The weapon releases a creature from its grasp early if you let go of the weapon or are incapacitated.

Thrown: If a weapon has the Thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the Finesse property.

Range: A weapon that can be used to make a ranged attack has a range shown in parentheses after the ammunition or thrown property. The range lists two numbers. The first is the weapon's normal range in feet, and the second indicates the weapon's maximum range. When attacking a target beyond normal range, you have disadvantage on the attack roll. You can't attack a target beyond the weapon's long range.

Versatile: This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.
