1. What is Attack Bonus?

Attack Bonus is a key mechanic in Dungeons & Dragons 5th edition that determines your character's chance to hit targets with weapon attacks and certain spells. It represents your character's combat training, physical prowess, and any magical enhancements.

2. How Does the Calculator Work?

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

Where:

• \( Proficiency\ Bonus \) — Based on character level (ranges from +2 to +6)
• \( STR/DEX\ Modifier \) — Strength modifier for melee weapons, Dexterity modifier for ranged weapons
• \( Other\ Bonuses \) — Any additional bonuses from magic weapons, class features, or spells

Explanation: The formula combines your character's training (proficiency), physical ability (STR/DEX), and any magical or special enhancements to determine how accurately you can strike opponents.

3. Importance of Attack Bonus Calculation

Details: Accurate attack bonus calculation is crucial for determining hit probability in combat. A higher attack bonus increases your chance to overcome enemy armor class (AC) and deal damage. It affects gameplay balance and character effectiveness in combat encounters.

4. Using the Calculator

Tips: Enter your character's proficiency bonus (based on level), the relevant ability modifier (STR for melee, DEX for ranged), and any additional bonuses from magic items or class features. All values should be integers.
