As you cast your Shielding Spell,
a bottle hits you on the shoulder.
You feel nothing.
Something is not quite right, and you try to cancel your Spell.
Unfortunately it has already been cast
and you can see the bottles smashing into the magic shield you have created.
The bottle which has hit you has disappeared.
You curse as you realize that the wine you just tasted
must have had some hallucinatory properties and you are imagining the bottle attack.
As this idea dawns on you, the bottles cease pelting you.
You blink and look again.
All the bottles are in place on their racks as normal!
