"Lunge's" Crusader's Fury Node Question

Hey all,

New player and loving the game so far. A question about the “Crusader’s Fury” node in the “Lunge” skill tree:

The tooltip says “after using Lunge, you gain additional physical penetration per enemy along the path.”

If I’m fighting a boss, does that mean that if I Lunge to him I won’t gain any additional physical penetration? Or will I still “hit him along the path” in the process of Lunging at him?

I ask because the Sentinel tooltips seem to explicity reference “along the path” versus “final” hit (for example, the bleeding node for Lunge “Rough Cuts” will bleed enemies along the path, but not the final hit).

Sorry if this seems like an obvious answer given the tooltip, I just want to make sure I’m not misinterpreting and therefore wasting points.

Thanks for any help!
