So, I was just realizing that some magic items grant powers from classes that include the Implement keyword. Does anyone know the details of how this works?
For example, if a Cleric uses a magic item that grants Magic Missile as an encounter power, can that Cleric use his holy symbol as the implement for that spell and gain any benefits granted by it (such as bonuses to attack and damage)?
I, personally, don't see why not, but I'd like some second opinions before I decide.
Let's say we have two half-elf rogues.
One takes the Arcane Initiate feat, which lets him use Magic Missile as an encounter power, and also grants him the ability to use a wand, staff, or orb as an implement when using a wizard power.
The other selects Magic Missile as his Dilettante power, which lets him use Magic Missile as an encounter power.
The first can use a wand as an implement when he casts Magic Missile; the second cannot.

Now let's say we have two half-elf clerics. One takes Thunderwave as his Dilettante power, the other takes Twin Strike.
We give each of them a Master's Wand of Magic Missile.
Power (Encounter Arcane, Force, Implement): Standard Action. As the wizard’s magic missile power (PH 159).
The first can use the wand's power; the second cannot:
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. The wand is arcane; the Thunderwave cleric can use an arcane power, but the Twin Strike cleric cannot. However, Magic Missile is an arcane spell, not a divine prayer, which means it needs a wand, staff, or orb (or rod) as an implement, not a holy symbol... and our half-elf cleric does not have the ability to use a wand, staff, or orb (or rod) as an implement. (If he'd taken Arcane (or Pact) Initiate instead, he could.)
Implement: Many arcane spells are more effective when used in conjunction with an implement—a wizard's staff, orb, or wand, or a warlock's rod or wand. Many divine prayers use holy symbols as implements.
I don't believe the cleric could use a holy symbol with an arcane spell; nor could he use an arcane implement without the Arcane (or Pact) Initiate feat.
