Fate of Disturbing Knowledge and Non-Remastered Skill Feats?

[rainzax]

As title.

What is the fate of Disturbing Knowledge which originally appeared in the Advanced Player's Guide but did not make the cut for the Remaster (it's not in Player Core).

Same question for similar skill feats.

Cheers!

I'm not sure I entirely understand your question.

All the non-reprinted material is still legal. (Although all cantrip damage got errated)

If material did get reprinted, you must use the new version.
