Question about the spirit energy

I have joined the vitality bros and became a Knight but I have a question:
Since spirit weapons imbue is being added will it add damage to vitality user’s damage?

We have no clue what spirit imbue does!

if you’re trying to say wether it adds damage to your attacks, that’s probably true in one way or another. maybe it adds a new DoT effect, maybe it gives true damage which can’t be blocked or something like that.
It simply wouldn’t make sense if it just added extra vfx and did nothing besides that

My two guesses for spirit imbuements:

  1. Attacks gain dual scaling
  2. Attacks will inflict a debuff depending on the spirit weapon imbued
