Baldur's Gate 3 is built on the Dungeons & Dragons Fifth Edition system, adapted for CRPG by Belgium-based developers Larian Studios. As with any tabletop-to-video game adaption, Larian has had to add, remove, and tweak the Fifth Edition rules to fit Baldur's Gate 3.

The most impactful changes that Larian Studios has made to the Dungeons & Dragons Fifth Edition system can be found in the game's core rules and mechanics:

  • The maximum level is 12
  • Multiclassing ignores Ability Score requirements
  • In Act 1, players will meet an NPC that can respec their characters
  • HP gained when leveling up uses the average result of the class' Hit Die
  • There is no cover system
  • When a character makes a ranged attack at a target at least 10ft lower than them, they get a +2 bonus. If the target is at least 10ft higher than them, they instead take a -2 penalty
  • Player characters with shared initiatives can act simultaneously
  • There are no Tool or Language Proficiencies
  • There are no Hit Dice, but Short Rests restore half of each character's HP
  • The party can only Short Rest twice between each Long Rest
  • Long Rests require Camp Supplies
  • Each Weapon type has a set of Weapon Actions that can be used once per Short Rest
  • Characters earn Inspiration based on their Background, and can only use it to reroll Ability Checks
  • Shoving, Jumping, and drinking a Potion are all Bonus Actions
  • Players cannot ready actions or grapple
  • Characters can throw other characters that are at least one size smaller than them
  • Bonus Action attacks, such as offhand attacks, do not require a main hand attack to be made first

  • Longer duration spells now last until the next Long Rest
  • Any character can cast a Spell Scroll, but only spellcasters get to add their Proficiency Bonus
  • Ritual Casting spells takes no additional time

The 11 Races of Baldur's Gate 3 can all be played in Dungeons & Dragons Fifth Edition, though some have received fairly major changes:

  • All races get +2 and +1 to two Ability Scores of their choice, rather than their racial bonuses

  • Drow are no longer weaker in sunlight
