1. What is Spell Attack Bonus?

Spell Attack Bonus (SAB) is a key mechanic in tabletop RPGs like Dungeons & Dragons that determines how likely your spells are to hit their targets. It combines your character's training (proficiency) with their innate magical ability.

2. How Does the Calculator Work?

The calculator uses the Spell Attack Bonus formula:

Where:

• \( Proficiency \) — Character's proficiency bonus based on level
• \( Ability Mod \) — Modifier from your spellcasting ability score (Intelligence for Wizards, Wisdom for Clerics, Charisma for Sorcerers)

Explanation: The formula represents your character's combined magical training and natural talent for landing spell attacks against enemies.

3. Importance of Spell Attack Bonus

Details: Spell Attack Bonus is crucial for spellcasters as it directly affects your chance to hit with attack roll spells. A higher SAB means your spells are more likely to connect and deal damage or apply effects.

4. Using the Calculator

Tips: Enter your character's proficiency bonus (typically +2 to +6 based on level) and your spellcasting ability modifier (based on your primary spellcasting ability score). Both values must be valid integers.
