Need Quick input for Tonights Game - Saving Throws

[JDragon]

Ok, Sorry to throw this out this late in the afternoon. I have a little over an hour till I leave to run my game and need the boards thought on something.

Should players roll all saving throws themselves?

Or is it ok for the DM to roll for them if the character is not aware?

Reason: the party is going to becoming in to possesision of an evil artifact tonight that has a chance of possessing them and changing their alignment. The PC's will not be aware of this and who ever has it, has to make a Will save once every 24 hours to resist its power. Each day the DC gets tougher.

Totally ok for the DM to roll if PC is not aware.

What I do is have the players roll most saving throws, but I will roll ones they don't know about. Keeps them on their toes.

Thanks for the input guys.

Thats what I was leaning toward but just wanted to check.
