What if the Ogryn had two rocks in both hands, and was bashing people with them?
Then as a special you throw them.
The throw is inaccurate compared to the grenade version of the rock, it falls much quicker, but fires much much faster.
Once you spend your rocks. To reload you slow down significantly, we hear grunts like you’re reaching the floor, and then you find two more rocks.
When you hit with rocks you deal a good balance of impact and strike down damage.
When you lose the rocks, you shift that hand into more impact then damage.
When both are gone you just deal significant impact damage, the special now is a parry that looks like a grapple, it knocks down if successful.
Also yes this is 100% a reference but also legit as a concept for a weapon thats in the vein of the grenade gauntlet.
