[1.2.133] Archer Jump!

Thanks for the responses. Another question I have is whether mastery books turn into the skills with brand new IDs. Like, some skills keep their old skill ID, but just change in what they do. An example of this is a Bishop's Holy Shield becoming Advanced Bless. Different skill, same ID. So the Holy Shield book most likely becomes the Advanced Bless book.

My question is: what if the skill ID is deleted, and the new skill has its own ID? For instance, Bishops have Mana Reflection deleted, and they gain the new skill (and ID) for Arcane Aim, right? So in this case, would Mana Ref book still become Arcane Aim book? Confirmation from KMS players appreciated.
