Flanking (Optional Rule)

Flanking (Optional Rule)

• Optional Rule
• Two creatures are flanking an enemy when they are on directly opposite sides of it
  • Both must be able to attack the enemy (in reach, not incapacitated, etc.)
  • Both must be on the ground (not mounted, flying, etc.)
• Both flanking creatures have advantage on melee attack rolls against that enemy
• Flanking only works with melee attacks
• Large or larger creatures only need one of their spaces to qualify for flanking
• A creature with reach greater than 5ft can flank from beyond 5ft if its reach allows
