The clutch claw allows hunters to use the slinger to attach themselves to the side of a monster sort of like the Switch Axe’s special move.
Using the Clutch Claw
Redirecting monsters: You can force monsters to go a certain way or direction as they try to shake you off. This opens up additional strategic options like, say, guiding a Diablos toward a special wall to get its horns stuck or any large monster toward a trap to hold it in place.
Flinch shot: Lets you unload all your slinger ammo in one go while you’re attached to a monster’s head to make it flinch, topple or slam into a wall.
