Resting

Resting is a gameplay mechanic used to restore lost hit points and depleted resources.

Rests can be either long or short. Long rests restore all lost hit points and spent resources, whereas short rests restore a limited amount of hit points, and a smaller variety of resources.

Long rest

Starting a long rest at camp

Long rests are primarily taken at camp and restore the following:

• All hit points
• All spell slots
• All resources
• Use of certain item actions
• Illithid power dialogue options

Partial rest

Taking a long rest passes the night, and costs 40 (80 in tactician or honour difficulty) camp supplies. If the party lacks the required supplies, they may instead take a partial rest, which restores the following:

• Restore hit points up to half of their maximum.
• Restore resources up to half of the character's maximum, rounded down.
  • This includes class-specific resources such as spell slots, Ki Points, and Superiority Dice.
• Refreshes cooldowns, including items, and class features like Song of Rest or Portent and most illithid powers.
  • Luck of the Far Realms is not restored as it costs a hidden resource you only have a max one of, which gets rounded down to 0.

Short rests are not restored when performing a partial long rest.

• Song of Rest does.

Many origin, companion and camp follower interactions will occur when long resting. Long rests can also advance certain time-sensitive content.

Short rest

Twice per long rest, the party can take a short rest, which restores the following:

• Hit points up to half of their maximum (rounded down)
• Uses of weapon actions
• Warlock spell slots
• Clerics regain their Channel Divinity charges
• Druids regain their Wild Shapes
• Paladins regain their Channel Oath charge
• Fighters regain the use of their Action Surge and Second Wind abilities, and their Superiority Dice
• Bards of level 5 or higher regain their Bardic Inspiration charges
• Monks regain their Ki
• The following Illithid Powers: Psionic Overload, Force Tunnel, Stage Fright, Repulsor, Shield of Thralls, Black Hole, Absorb Intellect, and Fracture Psyche

The Bard ability Song of Rest has all the same effects as a short rest. Note that characters that are not in the active party do not benefit from short rests; they do not regain hit points or resources.

Additional Types

There are additional features ingame which function similarly to taking a rest;

• The level 2 Bard feature  Song of Rest functions as a short rest.
• Potion of Angelic Reprieve functions as a short rest (in addition to recovering all expended and Spell Slots), if the character consuming it is left asleep, uninterrupted, for 2 turns.
• Potion of Angelic Slumber functions as a long rest, if the character consuming it is left asleep, uninterrupted, for 2 turns.
•  Divine Intervention: Opulent Revival restores the party as if they took a long rest, revives any downed party members, and can even be used in combat. However, any form of Divine Intervention can only be used once per character in the entire game.
• Using a Restoration Pod found aboard the Nautiloid in the prologue or the Mindflayer colony in Act Two, or the boudoir in the House of Hope in Act Three will restore the party as if they took a long rest, without ending relevant effects like  Goodberry or Elixirs.
