Primary Attack (Atk)

If a creature moves more than 5 feet in the same round it attacks, it makes only a single attack using its primary attack bonus. This bonus includes modifications for size and Strength (for melee attacks) or Dexterity (for ranged attacks). A creature with the Weapon Finesse feat can use its Dexterity modifier on its primary attack. The damage and primary weapon type are noted in parentheses.
A creature's primary attack damage includes its full Strength modifier (1.5 times its Strength bonus if it is the creature's sole attack).
Use the creature's primary attack bonus whenever the creature makes an attack of opportunity.
Creatures can attack with natural weapons, manufactured weapons, or sometimes both.
