Q. If a model declares the Onslaught Trigger during the same Action where its target declares the Regret Trigger, does the model still get to take the Attack generated by Onslaught?
A. Yes. Regret ends Step 2 (Taking Actions) of the Activation Phase and forces the model into Step 3 (End Activation).
