The Antimagic Ray is a spell originally from Draconomicon, updated in the Spell Compendium. Here's all the extracts from the text we need to analyze the case, or so I believe.
The target functions as if it were inside an antimagic field (PH 200).
If this spell is used against a creature, the subject can’t cast spells or use supernatural or spell-like abilities, nor do such abilities have any effect on the creature. However, the creature can still use spell completion items or spell trigger items, even though it can’t cast the spells required.
The spell doesn’t affect any objects other than the subject itself, even if those objects are worn, carried by, or in contact with the subject. For instance, if a creature is the target, its equipment remains unaffected.
The problem is, what happens when a +2, flaming longsword is used against the target of such a spell? I'll list each possibility my group came up with, along with with the reasons that make each valid.
the weapon works normally.
- the weapon is not in an AMF itself, nor its wielder is is.
- the weapon enchantments are neither spells, nor spell-like effects, nor supernatural effects, which the recipient is explicitly immune to.
the weapon behaves like a masterwork longsword.
- The target, if struck, functions as if it were inside an antimagic field can be read as "imagine an AMF around the target. When something tries to do something to him (like the sword attacking him) consider him to be in the radius of an AMF spell", so if the weapon is used to attack him, it's treated as if it was in the AMF. Would this be some sort of physical area attack, every other target would be hit by the fully magical weapon.
the weapon is magical as long as it's still hitting.
- A weapon hitting the target is not just "in contact" with it. Be it a piercing, slashing or bashing weapon, it's getting in the personal space of the target, that's considered a person-shaped AMF zone. So its +2 to hit still works (it's aiming at the spot, which happens before the weapon gets in touch) but no bonus damage is dealt.
all the enchantments that modify the effectiveness of the weapon still work, those who deal damage to the target don't.
- the weapon is still a powered up weapon that helps the wielder get a better swing, including +2 to hit and +2 to damage. But the flames, those are magic flames that don't even harm the wielder so they're clearly magical and won't work on the target when he gets hit.
So, is there a correct interpretation?
If not, is there a commonly recognized take on this issue?
