Help making shock-wave

So I have made a pretty good capture the flag map, but my friend wants me to add a shock-wave. Since there isn’t a gadget for this I need help with making a shock-wave that deals damage and breaks dynamic stone.

well button >>>>>relay all players>>>>>>deal damage Damager
but the stone part iDk

The breaking Dynamic Stone part is tricky (if not impossible)
But I think you can use this guide:

Just replace the “Poison Fog” with a shock wave animation
