Cleaving

You swing in wide, terrifying arcs:

• Increase your Strength by 1, to a maximum of 20.
• When you make an attack with a weapon that uses
  Strength you target a 5-foot cone in front of you
  originating from your square. Make one attack roll
  against each creature’s AC. You deal damage as
  normal to any you hit. This attack can hit, at most, 3
  creatures at a time. You may only cleave once per
  turn.
