1. What is Attack Bonus in D&D 5e?

The Attack Bonus in Dungeons & Dragons 5th Edition represents your character's chance to hit a target with weapon attacks or spell attacks. It combines your proficiency with the weapon/spell, your relevant ability modifier, and any other bonuses from magic items, class features, or spells.

2. How Does the Calculator Work?

The calculator uses the D&D 5e attack bonus formula:

Where:

• \( Proficiency \) — Your character's proficiency bonus based on level
• \( Ability\ Mod \) — Ability modifier calculated as: floor((Ability Score - 10) / 2)
• \( Other \) — Additional bonuses from magic weapons, class features, spells, etc.

Explanation: The attack bonus is added to your d20 roll when making an attack. If the total equals or exceeds the target's Armor Class (AC), you hit!

3. Importance of Attack Bonus Calculation

Details: Accurate attack bonus calculation is crucial for determining your character's combat effectiveness. A higher attack bonus means you're more likely to hit enemies, making your character more reliable in combat situations.

4. Using the Calculator

Tips: Enter your proficiency bonus (based on character level), the relevant ability score (Strength for melee weapons, Dexterity for ranged/finesse weapons, spellcasting ability for spells), and any additional bonuses. All values must be valid integers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for attack bonuses?
A: At level 1, attack bonuses typically range from +3 to +7. At level 20, they can reach +11 to +17 or higher with magic items.

Q2: How do I know which ability score to use?
A: Melee weapons use Strength, ranged weapons use Dexterity, finesse weapons can use either, and spell attacks use your spellcasting ability (Intelligence, Wisdom, or Charisma).

Q3: What if I have multiple sources of "Other" bonuses?
A: Add all relevant bonuses together - magic weapon bonuses, fighting style bonuses, class feature bonuses, and spell effects (unless they specify they don't stack).

Q4: Does this work for both weapon and spell attacks?
A: Yes! The formula is the same for both weapon attacks and spell attacks, though the ability score used may differ.

Q5: What about advantage or disadvantage?
A: Advantage/disadvantage affects the dice roll mechanics but doesn't change your attack bonus calculation. They are separate mechanics.
