Hello there, another approach that worked well for me:
Create an actor with a capsule component blocking all and a rotating component.
Set its lifespan to 0,1 -0,2
Spawn it on line trace or from your hit location.
The rotation will cause physical damage to the collection.
The damage is depending on rotationspeed and mesh size/shape.
Additionally another projectile component is an option to add directional impulse.
May it be of use for someone out there!
Stay creative
