2024 Fighter Question: Indomitable

"If you fail a saving throw, you can reroll it with a bonus equal to your Fighter level."

I have a question regarding the above. Is the "bonus equal to your Fighter level" in addition to your usual saving throw modifier, or used in place of it? So if you failed a Wisdom saving throw (SV bonus +3), would a 9th level fighter then roll 1d20+9, or 1d20+12?

It's with all of the bonuses from your normal save with the fighter level bonus on top. You are still rolling the same saving throw, but you get to expend a resource to give it a big boost.

The bonus equal to your Fighter level stacks with your saving throw modifier, so your Wisdom saving throw would get a +12 bonus to the roll.

This is a very powerful buff on it's own, but compared to the 2014 version of Indomitable (which gives you a reroll with no extra bonus) it is vastly superior.
For example, a Level 9 Fighter with 20 DEX fails a saving throw. They  expend their Indomitable feature in order to reroll the saving throw. Their new total is
[Result on die] + 5 (DEX) + 9 (Indomitable)  for a total bonus of 14 to the die roll.
If the character has proficiency in Dexterity Saving Throws, by taking the Resilient Dexterity feat for example, then they would add their proficiency bonus to that roll as well, for a total bonus of 18 to the roll.

Let's say that this Fighter has to avoid a dragon's breath weapon with a DC 25 DEX save.

• A standard roll, without proficiency succeeds on a 20, for a 5% success rate.
• Using Indomitable after a failure, without proficiency, succeeds on an 11 or higher, for a 50% success rate.
• A standard roll, with proficiency, succeeds on a 16 or higher, for a 25% success rate.
• Using Indomitable after a failure, with proficiency, succeeds on a 7 or higher, for a 70% success rate.

If you combine the initial chance of success with the chance of success after Indomitable, you get the following results:

• Without proficiency: 52.5% success rate - 5% chance of success + (95% chance of failure to use Indomitable x 50% chance of success on Indomitable roll)
• With proficiency: 77.5% success rate - 25% chance of success + (75% chance of failure to use Indomitable x 70% chance of success on Indomitable roll)
  For comparison to 2014, the success rate without proficiency is only a combined 5.475%. With proficiency, it is only 43.75%.

Keep in mind that this also works with Death Saving throws, making for the constant, and best, comparison between 2014 and 2024 Indomitable.
Rolling a 1 will still result in a critical failure, regardless of any bonuses, and your character will take 2 Death Saving Throw failures as a result. However, rolling a 2 or higher will result in a success with the 2024 Indomitable bonus. This gives you an overall 97.75% success rate on any Death Saving Throw as long as you have one use of Indomitable to expend on a failure. With the 2014 version not giving you a bonus to the reroll, your overall success rate is only 79.75%.

I hope you found this helpful and can use the formulas to your advantage with other characters in the future!

Does anyone have a link to an official ruling on this? Cause if it's saving throw + fighter level, that's disgustingly over powered compared to the 2014 rules. Whereas if it's a save using your fighter level, which would be a minimum of 9 cause it's a level 9 ability, that's better than the 2014 rules without being OP.

Right now, all i'm seeing is people's interpretation of the wording, which could be taken either way, and i've seen it taken both way.
