Arcane Implement Proficiency

Heroic Tier
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.

Update (11/23/2009)
In the first sentence of the first paragraph of the Benefit line, remove “other than your own.”
