Short Rest: spend recovery dice after completing the hour

SRD 5.2.1 · Rest

At the table

1. Begin with at least 1 Hit Point and spend one hour in permitted light activity.
2. On completion, spend a Hit Point Die, add Constitution modifier, and regain at least 1 Hit Point for that die.
3. Decide after each roll whether to spend another; Initiative, non-cantrip casting or any damage interrupts the rest and removes its benefits.

Example decision

A resting character spends a Hit Point Die and rolls 1 while having Constitution modifier −2. Under the rest’s minimum, how many Hit Points does that die restore?

One, because each spent die restores at least one.

The arithmetic total would be negative, but the entry sets a minimum of 1 Hit Point. After this roll, the player can decide whether another die is worth spending. The rest must first be completed; an interrupted Short Rest confers no benefits, so its expected dice recovery should not be credited early.

Watch for this mistake

A Short Rest does not automatically restore all Hit Points or spent Hit Point Dice. Read the benefits here and any class feature that recharges on a Short Rest.

Ask the table

Has the hour completed, and does the next recovery die need to be spent?
