Invisibility and the spell 'Break'

[Xaosist]

I was looking at spells that could be viable to use from invisibility to effect a combat outside of the usual summon monster and came across this:

Now invisibility states:

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.

But also calls out:

Actions directed at unattended objects do not break the spell.

So my question is - if I am targeting an attended object (a weapon in hand or some worn armor) but that spell isn't 'targeting a foe' (it specifically targets the object) and doesn't have an 'area or effect includes a foe' does the spell break the invisibility?

I know the save would be based on the creatures save as it is not an unattended object, but is this enough to break the invisibility spell?

The item is attended, and thus the spell will break stealth. If you were invisible and did that to a door or table, you would still be invisible.

Is there a section in the rules I can refer to for this?

[RumpinRufus]

Since the foe is attending the object, he gets to make a saving throw. Because he is making a saving throw, I would say the spell counts as targeting him.

Mostly I was pointing out the unattended object clause and the weapon being attended and thus not qualifying.

Yeah, the rules you quoted in the first post.

[Xaosist]

So any attended object being targeted would break the invisibility such as mend on an allies attended object?

[Dafydd]

Not quite.

If you are attacking (breaking a foe's sword is an attack) you break stealth. Debuffing a foe is also an attack.

If you are buffing or healing, such as mending an ally's sword, your invisibility would not break.
