Excessive Violence timing

[Ay Ay Ron]

Question about the ‘before damage’ effects for excessive violence. When does Bob take the 3 damage if he doesn’t have a dazed token? Is it immediate after the throw or after step 14 of the attack sequence. 
 

If bob takes the damage at step 11 does that immediately end the attack, negating the damage calculated in step 10?

Cheers.

He takes the damage and is likely Dazed during step 11. 

The damage will still finish in step 12 as it normally would.
