Lord Raven: The description for Arcane Eye is ambiguous, but since it doesn't list AC or HP I would assume the sensor can't be damaged (though it could be dispelled). However, we can easily sidestep the whole issue. Use a Move action to move the eye 30 feet straight up, which will take it out of the fireball AoE, then use a Standard action to cast the spell. You can still take the 5-foot step since you didn't use your Move action to actually move. All set. Spell will go off when I do the round, but that won't likely be until at least Monday.
Hopefully Jdvn1 won't be delayed any longer than that. It looks like Houston is going to get hit pretty hard. Best wishes to him and everybody there.
