Legacy utilizes three distinct time scales to handle different aspects of gameplay.

Rounds are the smallest time scale used in the game, specifically for handling the ebb and flow of combat encounters. With each round being 10 seconds long, it allows for a granular approach to tactical positioning, action economy management, and resolving the back-and-forth of attacks and abilities.

A round begins when the first character takes their turn, and ends when all characters have taken one turn.

The minute time scale is used for less intense situations, such as exploring environments, interacting with NPCs, or undertaking tasks that require more than just a few seconds but don't warrant tracking every ten-second increment.

Finally, the hourly time scale comes into play for long-term activities like resting, traveling long distances, or spending time between adventures or quests. Tracking time in hours for these situations avoids getting bogged down in too much minute-by-minute detail when it's not necessary.

Resting in particular often requires tracking elapsed time to determine when resources or abilities renew.

Short Rests last one hour, and each character can select one hour-long action that has the Rest property.

Long Rests last twelve hours, but each character will spend time sleeping and eating, leaving them three hours for actions that have the Rest property.

Actions that do not have the Rest property cannot be taken during the rest, unless the character wants to forego the benefits of taking that rest.
