Mark of a Hero

You have the willpower of a hero, the ability to push harder when times are tough. You gain the following benefits:

Heroic Action. You can push yourself beyond your normal limits for a moment. On your turn, you can take one additional action. You gain [roll]1d4-1[/roll] levels of exhaustion at the start of your next turn.

Once you use this feature, you must finish a long rest before you can use it again.

Heroic Resolve. If you fail a saving throw you can expend your Heroic Action to choose to succeed instead. You immediately gain [roll]1d4-1[/roll] levels of exhaustion.
