Weapon Shift: What exactly carries?

[Rageling]

I'm sure most of us know the feats in this chain, so let me cut to the core: What about things that effect the weapon itself?

The weapon melds into your natural attacks.

What if you have specific feats or abilities that apply to the fused weapon? Would you gain those as well?

I mean things like Weapon Focus/Specialization, Improved Critical, or even more specific things like an Inspired Blade Swashbuckler's specific version of finesse?

I've read them over multiple times, and my best takeaway is a strong "maybe."

Thoughts and/or Cited Things?

Thanks!

strong "no". there's really no room for argument.

weapon shift: damage type and weapon properties (with some exceptions). nothing else.

improved weapon shift: weapon special abilities, like Flaming and Bane. nothing else.

greater weapon shift: enhancement bonus. nothing else.
