In the Pathfinder Roleplaying Game, determining a character’s ability to hit in melee combat relies on a specific formula. This involves adding several key factors: the character’s base attack bonus, their Strength or Dexterity modifier (depending on whether the attack is made with Strength or Dexterity), and any relevant size modifier based on the creature being attacked. For example, a Medium creature attacking a Large creature would incur a -1 penalty to their attack roll. Conversely, attacking a Small creature would provide a +1 bonus.
Accurate melee attack resolution is crucial for successful gameplay. This process ensures fair combat encounters and allows players to strategically build and equip their characters for optimal performance. Understanding the underlying math allows players to predict outcomes and make informed tactical decisions. This system, derived from earlier editions of the game, provides a structured framework for adjudicating melee conflict.
