How to Use the Baldur’s Gate 3 Build Calculator

The BG3 Build Calculator is designed with simplicity and functionality in mind. It allows you to customize your character step-by-step, previewing your stats and progression as you go.

Step-by-Step Guide:

  1. Select Your Race and Subrace
    Start by choosing your character’s race — such as Human, Elf, Dwarf, Tiefling, or Githyanki. Each race grants unique bonuses like extra movement speed, resistances, or skill proficiencies.
  2. Choose a Class and Subclass
    Select from the main classes like Fighter, Wizard, Cleric, Rogue, Bard, and more. Then, pick a subclass (e.g., Battle Master, Warlock’s Fiend, or Paladin’s Oath of Devotion) to define your character’s unique playstyle.
  3. Assign Ability Scores
    Distribute points among six core stats:
    • Strength
    • Dexterity
    • Constitution
    • Intelligence
    • Wisdom
    • Charisma
      Use the calculator to see how different distributions affect your combat power, saving throws, and skills.
  4. Select Skills and Background
    Choose backgrounds such as Soldier, Acolyte, or Sage that provide skill proficiencies and roleplaying flavor.
  5. Pick Feats and Level Progression
    As your character levels up, you can add feats and class abilities. The calculator visually displays how each level adds new features, helping you plan ahead.
  6. View Build Summary
    Once all fields are selected, the tool generates a detailed summary of your build, including modifiers, spell slots, and combat bonuses.
  7. Save or Share Your Build
    You can save your build for future reference or share it with friends and the BG3 community to discuss optimization and gameplay strategies.

Formula and Mechanics Behind the Build Calculator

The Baldur’s Gate 3 Build Calculator uses the Dungeons & Dragons 5th Edition (D&D 5e) ruleset as its foundation. The formulas behind the tool replicate how the game calculates bonuses and abilities.

Here are some of the key mechanics it uses:

1. Ability Modifier Calculation

Ability Modifier = (Ability Score – 10) / 2 (rounded down)

Example:
If your Strength is 16, then Modifier = (16 – 10) / 2 = +3.

2. Attack Bonus

Attack Bonus = Proficiency Bonus + Relevant Ability Modifier

Example:
If you have a proficiency bonus of +2 and a Strength modifier of +3, your total attack bonus is +5.

3. Saving Throw

Saving Throw = Proficiency Bonus (if proficient) + Ability Modifier

4. Spell Save DC

Spell Save DC = 8 + Proficiency Bonus + Spellcasting Ability Modifier

5. Armor Class (AC)

Armor Class = Base Armor + Dexterity Modifier (if applicable) + Shield Bonus

These formulas allow players to understand exactly how each stat or feat influences their in-game performance.

Example Build Using the Calculator

Let’s walk through an example of using the tool to make a Half-Elf Paladin (Oath of Devotion) build.

Step 1: Race – Half-Elf (grants +2 Charisma, +1 Strength, +1 Constitution, and Darkvision)
Step 2: Class – Paladin (focuses on melee damage, healing, and divine powers)
Step 3: Ability Scores:

  • Strength: 16
  • Dexterity: 10
  • Constitution: 14
  • Intelligence: 8
  • Wisdom: 10
  • Charisma: 16

Step 4: Feats – Great Weapon Master (increases damage potential).
Step 5: Background – Soldier (proficient in Athletics and Intimidation).

Result:
A durable, high-damage melee build that excels in both combat and social encounters.

This is just one of thousands of possible combinations the Baldur’s Gate 3 Build Calculator can generate.

  • Plan Multiclassing Early: Some class features depend on level progression (e.g., Paladin’s Aura).
