Accurate wand

Cost: 20 gp

An accurate wand is a smooth and straight length of light wood, honed to a point at the tip.

Accurate (You gain a +1 bonus to attack rolls made with an accurate implement.).

Wand (A wand is a slender, tapered piece of wood, enchanted to channel arcane energy. If you are a member of a class that can use a wand as an implement, you can apply the enhancement bonus of a wand to the attack rolls and the damage rolls of any of your powers from that class that have the implement keyword, and you can use a wand’s properties and powers. Members of other classes gain no benefit from wielding a wand.
Using a wand’s power works like using the power normally. To do so, you need to be able to use at least one power from the same power source as the wand.
For example, a rogue who has picked up at least one wizard power through multiclassing feats could use a wizard power in a wand, since each knows one power that uses the arcane power source. Several wands appear below, but you can also design your own.
A wand can contain an encounter power of any class capable of using wands. When you craft a wand, you can choose any encounter power that you know or that is available to your class. You can’t choose anything other than a class power (you can’t choose a paragon path power, for instance).
