Valerie Diaz question

"If Valerie is in combat with a vampire you can burn 1 pool once each round to make her immune to all non-aggravated damage from a strike or damaging effect."

So "A strike or damaging effect."
That's singular, not plural.

So, let's say she's rushed by Enkidu. Big crows, plus hands. You can only prevent the 3 hands or 2 birds, right?

Because wording?

No,
Because of en.wikipedia.org/wiki/Logical_disjunction
