Can I use Heroic Inspiration in Death saves?

Hi there, Midgardians!

So my question is: can a player spend their Heroic Inspiration in a Death save roll?

Thanks in advance.

Yes.

From the glossary:

If you (a player character) have Heroic Inspiration, you can expend it to reroll any die immediately after rolling it, and you must use the new roll.

It's not restricted to d20 tests, or even to rolling d20s. If you wanna reroll one die out of a damage roll, that's legit.

Death saves are totally within its mandate.

Yes. You can use it on literally any die rolled for any purpose. The only restriction is that it only applies to dice you roll, and not things like saving throws enemies roll against your spells.

Some of the weirder things you can use it on include, but are not limited to:

• Wild Magic Surge table rolls
• The d6 roll to see whether a Mirror Image duplicate takes a hit for you
• A Diviner Wizard's Portent Die
• The d6 roll to see whether Blink affects you
• Drawing a card from the 5.5e version of the Deck of Many Things

There's actually a trend throughout the 5.5e rules of a few things that were previously specified as being randomly determined by drawing cards or flipping coins now being specified as die rolls instead, probably to give you more chances to use this.

Thank you very much, guys! ❤️

• Wild Magic Surge table rolls

 I should mention that you have to reroll both dice when you're rerolling a d100, because it's really one die.

Just to add the Wish case: Interaction between Heroic Inspiration and Percentage Chances

Technically, you can even use heroic inspiration when rolling to gain HP on level up, though I would personally house rule against that.
