Rewind time, what's the point

[Chromantic Durgon <3]

Rewind Time (Su): Once per day as an immediate action, you can reroll any one d20 roll that you have just made before the results of the roll are revealed. You must take the result of the reroll, even if it’s worse than the original roll. At 11th level, and every four levels thereafter, you can use this ability an additional time per day. You must be at least 7th level to select this revelation.

Why bother if you have to choose to do it before revealing the die role?

[Knight who says Meh]

Not the roll, the results of the roll. (Success or failure)

Yeah, it's a little tricky when you already know the number you need before you make the roll.

To clarifiy, you get to know what number has come up on the dice but must decide to use the ability before the GM reveals the outcome (i.e. success or failure) of the action.

For example, your party triggers a trap which releases a noxious gas into the air, requiring a Fort Save from yourself and your party members. You roll your d20 and are disappointed that you only get a '6', but do not yet know whether or not you have passed the DC or what the effect of a pass or save might be.

If you suspect that your result of '6' may not be high enough to pass the save and that the results of failure might be serious, you could choose to reroll your d20 in hopes of getting a result higher than a '6'.

Note that a nat 1 is always a failure - the real point of this ability is to reroll those auto-failures.

Also, if your last attack missed on a 6, and you rolled a 4, you could choose to use a reroll.

In either case, you know it's a fail but the GM hasn't announced it yet, so you can use the ability.

I see! Thanks everyone :)

A natural 1 is not always a failure. Only on attack rolls and saving throws.

The only time a Nat 1 is not automatically a failure is when you use skills. If you have UMD at 19, you can never fail to use a wand.

UMD specifically calls out natural 1s as auto failing when attempting to activate an item. So that's just a bad example.

No, if you roll a 1 AND you fail, you can't try again for 24 hours.

If you match or beat the DC with a 1, you succeed.

It does not say that, it says...

Meaning, if you roll a 1 and still succeed, you still activate the wand and can keep using it. (19+1=20) which is the DC needed to activate the wand.

Well I'll be damned. Thanks for the correction, man.

And ability checks. And caster level checks. And concentration checks. The dispel check for dispel magic. And anything else that does not say it autofails on a natural 1.

The only things that are affected by the Natural 1/Natural 20 rules are those things that specifically state that. The only things that do state that are attack rolls (and combat maneuver checks, as those are attack rolls) and saving throws. There is no generic "auto-fail on a natural 1 rule" anywhere. Only those things that specifically say so have that.
