I have a standing house rule that if you act suicidal, you will probably end up dead. If a PC falls 100 feet by accident, luck/skill/etc. hit points kick in and you take 10d6 falling damage. If the player has his PC voluntarily nosedives 100 feet, he splats at the end and rolls up a new character. Standing around in a fireball = full damage at the very least. You certainly aren't going to be able to successfully save against it.Better to say nothing at all in my view than to describe something for the player about their character doing something.
