Save that ends the effect

To those of you who gave honest comments thank you

However
1. Im insulted that some of you accuse/ trash me because I dont know my game group or that they cant roll d20 out of their ass.
Uh its my group, uh I said Ive watch them.
Conclusion you would like to be a butt head for the heck of it or can not read.

The reason people are skeptical is that, unless you believe in the existence of some form of mystical good fortune effect, there are only three possible explanations - a temprary statistical anomaly, cheating on dice rolls, or observer error.

If it's a statistical anomaly, then it could end today - luck has no memory.

If there's cheating going on, altering the rules won't help, because people aren't playing by the rules.

And if it's observer error, there wasn't a problem in the first place.

In none of these cases will decreasing the chance of succeeding on a saving throw have any positive effect.

And if we allow the possibility of some form of supernatural 'good fortune' effect upon your players, there's still no guarantee that changing the odds will help you unless you can establish that supernatural effect as being constant and unchanging. It might just as easily alter its effects to match whatever change to the odds you introduce.
