Question on Invisibility (3.5)

[Illarion]

Ok, let me try to explain the situation. We have enemy A on the ground at -2 hit points, or something like that. Enemy B is adjacent to A and is invisible. We also have PC C adjacent to enemy B and is aware that B is there due to standing in the area of a Grease spell, so C can see B's foot prints in the grease. So, something like below.

|C |
|BA|

Now for the fun part, enemy B pulls out a wand of Cure Light Wounds and uses it on enemy A. Does the PC get an AoO on enemy B? Why or why not. Please state your sources as I will need to reference them in my argument.

I said that there would not be an AoO, because C cannot see what B is doing, thus cannot see when to make the AoO.

The counter argument was that activating a wand provokes an AoO and the book does not explicitly state the relation to Invisibility.

[ArqArturo]

I say there's no AoO, because of this:

The creature or object touched becomes invisible, vanishing from sight, even from darkvision. If the recipient is a creature carrying gear, that vanishes, too. If you cast the spell on someone else, neither you nor your allies can see the subject, unless you can normally see invisible things or you employ magic to do so.

Items dropped or put down by an invisible creature become visible; items picked up disappear if tucked into the clothing or pouches worn by the creature. Light, however, never becomes invisible, although a source of light can become so (thus, the effect is that of a light with no visible source). Any part of an item that the subject carries but that extends more than 10 feet from it becomes visible.

Of course, the subject is not magically silenced, and certain other conditions can render the recipient detectable (such as stepping in a puddle). The spell ends if the subject attacks any creature. For purposes of this spell, an attack includes any spell targeting a foe or whose area or effect includes a foe. (Exactly who is a foe depends on the invisible character’s perceptions.) Actions directed at unattended objects do not break the spell. Causing harm indirectly is not an attack. Thus, an invisible being can open doors, talk, eat, climb stairs, summon monsters and have them attack, cut the ropes holding a rope bridge while enemies are on the bridge, remotely trigger traps, open a portcullis to release attack dogs, and so forth. If the subject attacks directly, however, it immediately becomes visible along with all its gear. Spells such as bless that specifically affect allies but not foes are not attacks for this purpose, even when they include foes in their area.

Invisibility can be made permanent (on objects only) with a permanency spell.

Since he's not attacking a creature, despite the player knowing the enemy is there, he can't really do anything.

[TuggyNE]

There is no AoO. An invisible creature has total concealment, and total concealment makes AoOs impossible.
Total Concealment
[…]
You can’t execute an attack of opportunity against an opponent with total concealment, even if you know what square or squares the opponent occupies.

Open and shut.

[Illarion]

...and we are all wrong. Well, right, but for the wrong reasons.

Rules Compendium pg. 85. "In the Spell Trigger" section, it states "Activating a spell trigger item takes the same amount of time as the casting of the spell that the item stores, but activating the item doesn't provoke attacks of opportunity."


Either way, thank you for the feedback.
