1. What is Weapon Attack Bonus?

The weapon attack bonus in D&D 5e represents how skilled a character is at hitting targets with their weapon. It combines their natural ability (Strength or Dexterity) with their combat training (proficiency bonus).

2. How Does the Calculator Work?

The calculator uses the weapon attack bonus formula:

\[ \text{Attack Bonus} = \text{Proficiency Bonus} + \text{Ability Modifier} \]

Explanation: The formula represents how both training (proficiency) and natural ability contribute to a character's combat effectiveness.

3. Importance of Attack Bonus

Details: The attack bonus determines what you add to your d20 roll when making an attack. A higher bonus means you're more likely to hit your target. It's a key factor in combat effectiveness.

5. Frequently Asked Questions (FAQ)

Q1: How do I know my proficiency bonus?
A: It's based on character level: +2 (levels 1-4), +3 (5-8), +4 (9-12), +5 (13-16), +6 (17-20).

Q2: Which ability modifier should I use?
A: Use Strength for melee weapons (unless finesse), Dexterity for ranged weapons. Some weapons (like finesse weapons) can use either.

Q3: Do magic weapons affect this?
A: Yes, magic weapons typically add a bonus (+1, +2, +3) to both attack and damage rolls, which would be added to your total attack bonus.

Q4: What about the Archery fighting style?
A: The Archery fighting style adds +2 to attack rolls with ranged weapons, which would be added to your total attack bonus.

Q5: What's a good attack bonus?
A: At level 1, +4 to +5 is typical. By level 20, +11 is common without magic items. Higher is always better for hitting targets.
