Can the various Artificer powers that target weapon or implement
be used to affect a Monks hand/feet attacks, even though they are not a weapon like a Long Sword
?
UPDATE
Thinking on it, I suppose this is for both Monk attacks with their hand as a weapon, like Melee Basic Attacks
and attacks when they use an actual implement
UPDATE
The Weapon
reference in PHB2 and PHB3 makes it clear, You can use an unarmed attack as your weapon
