Homebrew: Heroic Inspiration

All characters begin a session with Heroic Inspiration. Characters who have submitted a session report since their last adventure also begin the adventure with an Inspiration Token.
Heroic Inspiration may be used in several ways:

1. To gain advantage on any d20 check, or to negate disadvantage.
2. To re-roll a failed d20 check.
3. To grant disadvantage to an attack roll targeting the character.

Making use of any option expends the characters Heroic Inspiration, causing them to lose it.
Characters without heroic inspiration regain it in two main ways:

1. Characters with one (or more) Inspiration Tokens may expend that token to regain Heroic Inspiration.
2. After rolling a natural 1 on a d20 check, characters without Heroic Inspiration regain it. They may immediately spend this Heroic Inspiration to re-roll the check, if they wish.
3. If a character does not have Heroic Inspiration, the GM may force that character to make one d20 check with disadvantage. If they do, that character gains Heroic Inspiration. Players may not use this Heroic Inspiration to re-roll a d20 check that was given disadvantage by the GM.
