D&D 5th: Lost Mine of Phandelver
There are three available types of rest within our DnD session. They are as follows:
A short rest is a period of downtime, at least one hour long. During this time, a character does nothing more strenuous than eating, drinking, reading, and tending to wounds.
Upon completion of a short rest, a character can spend one or more Hit Dice, up to that characters maximum number of Hit Dice (equal to their level). For each Hit Die spent in this way, the player rolls the die and adds their CON modifier to it, they then regain hit points equal to the total. The player may decide to spend an additional Hit Die after each roll. A character regains some of their spent Hit Dice upon finishing a long rest.
A half rest falls between short and long rests, taking four hours to complete. A character can restore up to half their expended spell slots at the end of a half rest, and also spend up to half their maximum number of Hit Dice to recover hit points. Both numbers are rounded down.
A long rest is a period of extended downtime, at least 8 hours long, during which a character sleeps or performs light activity: reading, talking, eating, or standing watch for no more than 2 hours. if the rest is interrupted by a period of strenuous activity- at least 1 hour of walking, fighting, casting spells, or similar adventuring activity- the characters must begin the rest again to gain any benefit from it.
At the end of a long rest, a character regains all lost hit points. A character also regains spent Hit Dice, up to a number of dice equal to half of the character's total number of them.
A character cannot benefit from more than one long rest in a 24-hour period and must have at least 1 hit point at the start of the rest to gain its benefits.
