Relax (PSR Supplement)
From D&D Wiki
Other Dangers |
You can relax as a downtime enterprise. When you do, you focus on leisurely activity or self-fulfilling hobbies, which inspires you for a little while.
After relaxing, once before your next downtime if you fail a save, check, or attack roll, you can choose to reroll the d20 and use the new result if it is higher. You can't gain this benefit if you already rerolled the d20 with another effect.
