Breaking an enspelled item

[niteowl24]

Imagine this scenario:

A group of humans are exploring a cavern and stumble across a group of drow fighters. The human cleric casts daylight on a stone to illuminate the area and give his companions an advantage. One of the drow then sunders the stone.

What happens to the spell?
a.) Would the spell persist on both halves of the stone, effectively giving you two spells?
b.) Would the spell persist on the larger of the two pieces only?
Or c.) Would it be negated by having the stone broken?

If the answer is a or b, then how badly damaged must the item be to negate the spell cast upon it?

Sundering does not (necessarily) split an item in half, so the presumptions of your first two options do not work for me.

I am going to take a wild guess that your vote is C, and that you are the GM that came up with the clever idea to break the rock your player's boned your NPCs with.

If I were the GM, I would say that sundering the rock doesn't work because it's silly. If I had to make a detailed ruling, I would say that one particular fragment of the rock would still glow (not both halves or every piece) and which fragment would be essentially random (i.e. not the largest).

It's not especially different from, say, cutting off a bad guy's arm. If the bad guy had Enlarge Person on, he's not going to suddenly shrink because you cut his arm off.

How badly must the item be damaged to negate the spell? It would need to be utterly obliterated, like a Disintegrate or acid or something. However, a much easier solution would be to just grab the rock and put it in your pocket, or throw a cloak over it.
