Well, thanks for being civil
I do tend to warn my players about such things well in advance and if they can't take a hint, for lack of a better word, thier loss. I don't place Bodaks in chests and I do researve SoD effects for special cases. Even when the party has protection I have the cleric try to dispell it and the following round the players know, if they can't kill the person with the SoD effect or they can't reprotect themselves, they will have to roll a save. I don't want to say I am a master of the SoD effect or anything, but I do use it to build tension and get the players, specailly the high levels ones that are immune to a lot of stuff you throw at them, a sense of fear and a knowing feeling that they could die if they don't keep a sharp mind.
So it is not that I protect or shield them from harmful effects, it is that I give them clues that something potenially deadly is coming up and if the PCs do a little probing they will usually be rewarded with a bit of knowledge and a good warning. Afterall, that is what the knowledge checks are for. Every SoD effect attached to a monster can be found out by a knowledge check and a little asking about the ancient tomb at the top of the hill will reveal rumors of who has lived and died there and what one might expect.
It would only be a true jackass of a DM who just off handedly throws SoD effects left and right.
Did that explain it better? I'm at work and short on time. If not I will try again later.
