"After Succeeding" timing clarification

[Mastershake]

If a trigger specifies "After Succeeding", does it take effect before or after the effect of the duel is applied?

Example: Lucius issues an order with the trigger to make a model take a (1) Interact Action after succeeding. Would the (1) Interact take place place before or after the normal (1) Action the model takes when the action goes off?

I'm assuming that will apply for all of the Riders. Awesome.

EDIT: How will this affect things like the Slug trigger that deal two separate instances of damage? Will it reduce both of them separately?

Df © Grave Whispers: Reduce the damage suffered by this model during this Action by 1 for each C in its final duel total, to a minimum of 1.

How will this affect things like the Slug trigger that deal two separate instances of damage? Will it reduce both of them separately?

Maybe remove the definite article from damage? That way it would clearly apply to all damage.

Slug occurs after the Action has resolved, since it has an 'after damaging' phrase. 'During this Action' would only apply to the original damage flip, so unless the intention of the rules is to block damage from the Action AND damage from the triggers, the wording is fine.
