Rod (If you are a member of a class that can use a rod as an implement, you can apply its enhancement bonus to the attack and damage rolls of any of your powers from that class that have the implement keyword, and you can use a rod’s properties and powers.

A rod is a short, heavy cylinder, typically covered in mystic runes or inscribed crystals. As with most other implements, you can’t make melee attacks with a rod.
