I think some of these exist already in some form, and if you could point me in the direction that’d be great.
But in the mean time:
Shockwave: Force explosions in a straight path in front of the player
Slam: Ragdoll a target, flies them up then slams them down.
Charge(not sure if this is possible): Player charges at a target and knocks them back, and can pass through props.
Singularity: Creates an area where anything enters it is ragdolled and floats freely around it.
