In the new Dragon Delves adventure anthology, Wizards of the Coast presents the following special ability. Supposedly, it is enough to allow a single PC to complete an adventure meant for the entire party.

>Blessing of the Lone Champion
>• Heroic Inspiration. You gain Heroic Inspiration when you finish a Short or Long Rest and whenever the DM has you roll Initiative.
>• Temporary Hit Points. You gain a number of Temporary Hit Points equal to 10 times your level when you gain this blessing and when you gain a level.

Is it really, though? Is this truly enough to compensate for having significantly less action economy and resources on hand?
