1. What is Attack Bonus in Pathfinder 2e?

The Attack Bonus represents your character's chance to hit a target in combat. It combines your character's level, relevant ability modifier (usually Strength for melee or Dexterity for ranged), and proficiency with the weapon or attack type.

2. How Does the Calculator Work?

The calculator uses the Pathfinder 2e attack bonus formula:

Where:

• Level — Your character's level (1-20)
• Ability Modifier — Modifier from your attacking ability (usually STR or DEX)
• Proficiency — Bonus based on your training with the weapon/attack:
  • Untrained: +2
  • Trained: +4
  • Expert: +6
  • Master: +8
  • Legendary: +10

3. Importance of Attack Bonus

Details: Your attack bonus determines whether you hit opponents in combat. Higher bonuses make you more likely to hit and potentially score critical hits (which occur when your attack roll exceeds the target's AC by 10 or more).

4. Using the Calculator

Tips: Enter your character level (1-20), the relevant ability modifier (usually between -5 and +10 for most characters), and select your proficiency level with the weapon or attack type.

5. Frequently Asked Questions (FAQ)

Q1: What ability modifier should I use?
A: For melee attacks, use Strength. For ranged attacks, use Dexterity. Some weapons have the "finesse" trait allowing you to use Dexterity for melee.

Q2: How does proficiency increase?
A: Proficiency increases as you gain levels and select appropriate skill/weapon feats. Your class determines your base proficiencies.

Q3: What's a good attack bonus for my level?
A: At level 1, trained characters typically have +7 (+1 level, +4 trained, +2-4 ability). This increases by about +1 per level.

Q4: Are there other bonuses to attack?
A: Yes, you might get circumstance or status bonuses from spells, conditions, or tactical advantages.

Q5: How does this differ from spell attack rolls?
A: Spell attacks use the same formula but with your spellcasting ability modifier instead.
