Probably with velocity 
:
Since you’re telling the CMC what to do, this will propagate to all other systems that rely on it - collision, friction, physical interactions and so on.
Another, more nuanced way:
- apply radial damage with Damage Type Class (make a new Displace class, lets say)
- use the damage type to preprocess damage values and have the recipient instead apply velocity change to itself:
As a massive bonus, you’ll get the Damage Prevention Channel (last pin of the top node) which will allow you to hide behind obstacles.
