Resting

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

Overview

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. Taking a long rest passes the night, and costs 40 (80 in tactician or honour difficulty, up to 120 in custom difficulty) camp supplies.

Full rest

If possessing the required supplies, the party can take a long rest, which restores the following:

• Hit points - all
• Spell slots - all
• Resources - all
• Use of certain item actions
• Illithid power dialogue options
• Both Short Rest slots

Partial rest

If lacking the required supplies, the party can instead take a partial rest, which restores the following:

• Hit points - up to half of their maximum, rounded down
• Resources - up to half of the character's maximum, rounded down
  • Including class-specific resources such as spell slots,  Ki Points, and  Superiority Dice
• Refreshing of cooldowns, including items and class features like Song of Rest, Portent and most illithid powers
  • Luck of the Far Realms is not restored as it costs a hidden resource which is a maximum of 1, and is rounded from one-half down to zero (0).

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

Consequences of long resting

Many origin, companion and camp follower interactions occur on long resting. Long rests can also advance certain time-sensitive content; additionally each act has a handful of quests which advance upon long resting.

Any Temporary bonuses with "Duration: Until Long rest" end.

Any effects of Elixirs end.

Short rest

Twice per long rest, the party can take a short rest without travelling to the camp. Characters who are not in the active party do not benefit from short rests and do not regain hit points or resources. Short rests restore the following:

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

Additional Types

There are additional features in-game which function similarly to taking a rest;

• The level 2 Bard feature  Song of Rest functions identically to 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 and uninterrupted, for 2 turns.
• Potion of Angelic Slumber functions as a long rest, if the character consuming it is left asleep and 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, the boudoir in the House of Hope in Act Three, or in High Hall, also in Act Three, restores the party as if they took a long rest, without ending relevant effects like  Goodberry or Elixirs.
