Arcane Implement Proficiency
Prerequisite: Any arcane class
Benefit: Choose a kind of implement associated with any arcane class. You can now use that kind of implement.
If that implement is also a weapon, you do not add the weapon’s proficiency bonus to attack rolls made while you wield it as an implement.
In the first sentence of the first paragraph of the Benefit line, remove “other than your own.”
