Power Attack

You can make exceptionally strong attacks with melee weapons at the cost of some accuracy.

• Increase your Strength score by 1, to a maximum of 20.
• Before making an attack roll with a melee weapon you are proficient with, you may subtract any number, up to 5, from your attack roll. This number cannot exceed your Strength ability score modifier. On a successful hit, you add that number to your damage roll.
• The penalty to attack rolls and bonus to damage rolls persists until the end of your turn.
