Issues with using Paragon character mesh & sockets

For example: (see attached pic)
From the Spawn Projectile Base widget, he casts to ThirdPersonCharacter then As Third Person Character he drags out to Weapon_Attached (his skeletal mesh of the weapon he created). From there he gets a reference to target skeletal mesh then Get Socket Location. The return value from Get Socket Location is them directed to the Location input of Spawn Emitter at Location.

This is the part that I cannot figure out. Obviously I didn’t create the Weapon_Attach BP because I’m using the Paragon mesh that already has the weapon attached to the skeletal mesh of the character.

So, how do I get an Emitter to reference the socket location of the skeletal mesh of the Paragon character’s pre-built weapon?
