Do you get bonus points at the end or during play for these quest rewards?
&quot;Whenever&quot; infers present tense, you score 2 VP at the exact time you complete a Warfare quest happens.
If it were to refer to end of game or count anything retrospectively then that would have been clearly stated.
I don't think the card would qualify for its own bonus.  The rules say.

To complete a Quest, remove the required Adventurers and Gold from
your Tavern. Return those tokens to the supply. Then collect the
specified reward.

&quot;Then collect&quot; happens after the mission was completed.  not during.

When you complete a Plot Quest, place its card face up near your
player mat to remind you of the ongoing effect.

So &quot;Whenever you complete a Warfare quest, you score 2 VP&quot; is an ongoing affect.  It's usually in games for this to mean from now on.  if it applied to itself and all retrospective missions it should state that clearly.
