Ratjaw Weapon Fusion
(from Starfinder Pact Worlds)
The ratjaw fusion aids in disarming and robbing foes. On a critical hit, the weapon knocks an item of your choice out of the target’s possession, as long as it something that could be removed with a successful disarm combat maneuver. If the weapon already has a critical hit effect, when you score a critical hit, you can apply either the weapon’s normal critical hit effect or this disarming ability. If the ratjaw weapon is a ranged weapon, the disarmed item lands in any square of your choice adjacent to the target. If the ratjaw weapon is a melee weapon, it draws the item to you, and you can grab the item with a free hand.
