If we legaly wield two weapons or implements, do we gain the Enchantment property from both? I've found this on it.
Player's Handbook p.225
Property: Some magic items have a special property that is constantly active (or active under certain conditions). A property doesn’t normally require any action to use, although some properties allow you to turn them off (or on again).
Update; Adventurer's Vault p.56
Weapon Property: Many weapons have properties that provide a constant benefit. To gain the benefit of a weapon’s property, you must be wielding the weapon. Unless specified otherwise, a property affects only the weapon to which it’s attached. For example, a +2 cunning dagger, which bestows a –2 penalty to an enemy’s saving throws against your weapon powers, affects only powers that are delivered using that weapon. You couldn’t hold the weapon in your off-hand and gain the benefit of the property on powers delivered using a main weapon.
Can a Warlock benefit from holding two rods? Yes, a warlock can gain the properties from two rods but he still can only use one to make an attack.
Player's Handbook p.239
Rods: 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. Members of other classes gain no benefit from wielding a rod. 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.
From what I can pull of this is that; Though the FAQ specifically mentioned "Warlock", the answer itself was for Implements in general since the entry for "Rod's" in PHB p.239 didn't mention any specific rule regarding this, so it works for Implements.
In PHB the rules on the magical properties was speaking of how a magical item's property functioned in general, as a result you could wield two magical melee weapons and benefit from the property of each, but after AV this hole was filled and this particular quality was granted to "Double Weapon's" at the cost of limiting versatility.
Have I missed something or is there a loophole that can be used?
