Attack Roll and D20 in Baldur’s Gate 3


Taking a swing at an opponent in Baldur’s Gate 3 relies heavily on the Attack Roll mechanic. When characters engage in battle, their actions necessitate the Attack Roll. The character, poised to strike, rolls the D20. If the rolled value meets or surpasses the target’s Armour Class (AC), then the attack successfully makes its mark, wielding the weapon currently at hand.

Exploring Attack Rolls in Baldur’s Gate 3

In the universe of Baldur’s Gate 3, the Attack Roll plays a pivotal role whenever a character is locked in battle with another. To measure the potency of an attack, the character on the offensive rolls the D20. Should the outcome of this roll match or exceed the target’s Armour Class (AC), the attack is deemed successful, hitting the target with the weapon equipped at that moment.

Unraveling Attack Roll Modifiers

In the combat arena, Melee weapons align with the Strength ability modifier, whereas Ranged Weapons are closely tied to the Dexterity ability modifier. Nevertheless, there are instances when the rules deviate, particularly with melee weapons possessing the finesse property. In these cases, Dexterity supersedes Strength.

The proficiency a character holds over their currently wielded weapon also plays a significant role in influencing Attack Rolls.

The Art of Damage Calculation

Successful strikes lead to the next stage – calculating the inflicted damage. Your Ability Modifier adds its value to your damage roll, serving as a crucial component of the damage calculation. In practice, damage rolls are the sum of the dice or die linked to the weapon used, plus the ability modifier. This implies a twofold benefit for those with high Strength or Dexterity: they’re not only more likely to land a successful hit with their weapon, but the damage they inflict will also be considerably higher.


Integral to the mechanics of Baldur’s Gate 3 is the D20, or 20-sided die. This game, inspired by the 5th edition of Dungeons and Dragons, leverages a system rooted in the roll of this unique die. The D20 is the linchpin to resolving encounters and scenarios within the virtual landscape. While the game’s algorithms manage these rolls behind the scenes, players can still observe the outcomes in the lower corner of the screen.

Decoding the D20 in Baldur’s Gate 3

In instances where actions’ outcomes hang in the balance, the game resorts to the roll of the D20. These rolls underpin the crux of determining success or failure within the game.

The game world is populated by characters and monsters, each defined by six ability scores: Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma. Adventurers generally possess scores ranging from 3 to 18, while monsters could have scores as low as 1 or as high as 30. The ability scores and their subsequent modifiers are the foundation of nearly all D20 rolls made on a character’s or monster’s behalf.

The game introduces target numbers for ability checks or saving throws as the Difficulty Class (DC), and for attack rolls as Armor Class (AC). It’s important to note that in Baldur’s Gate 3, any divided number that results in a fraction is rounded down, regardless of the fraction’s size. This rule presides over the resolution of the majority of tasks within the game.

The Dynamics of the D20

The game’s core mechanics begin with rolling the D20 and adding a suitable modifier. Usually, this modifier is derived from one of the six Ability Scores and may sometimes include a Proficiency bonus that reflects a character’s specific skill set. Following this, circumstantial bonuses and penalties get factored in. These could arise from a Class Feature, a Spell, a certain circumstance, or some other influencing effect.

The total is then compared to a target number: a successful ability check, Attack Roll, or Saving Throw is one where the total equals or exceeds the target number. On the flip side, if the total falls short, it’s considered a failure.

Influencing Dice Rolls: Empowering Players

The game offers the power to influence the outcome of dice rolls. To heighten the probability of successfully surpassing a check, players can manually add their or their Companions’ Spells to their throw. Bear in mind, however, that casting a Spell consumes Spell Slots, urging players to choose wisely. These bonuses are compounded with existing ones (from Proficiencies or Abilities), with the aggregate sum added to the roll.
