The Hand Hook is a meleeweapon exclusive to the Queen and the Sea DLC with a 2 hit combo. The last hit of the combo throws the hit enemy behind you dealing knockback to enemies it hits. When the thrown enemy hits a wall it receives critical damage.
Details
Special Effects:
The last attack of a combo throws the enemy backwards. If the thrown enemy hits a wall or another entity, it and any other enemies that stand by the wall receives critical damage.
Enemies that are thrown into friendly critters (such as Mushroom Boi!TBS, LeghuggerTQatS, Maria's CatRtC, or pink biters from sources such as Swarm) will receive critical damage as if they hit a wall.
Thrown enemies will almost always impact the pet Maria's CatRtC if he is seated on your shoulder, taking critical damage.
Thrown enemies will take critical damage if they impact the deployable Emergency Door.
Enemies such as The Concierge can be stun locked by repeatedly throwing them with Hand Hook.
Grappling Hook and Scheme can be used together in conjunction with this to provide a more consistent and damaging version of this method.
