The chief tactical virtue of the flail is its capacity to strike around a defender's
shield or parry.
Melee: This weapon can be used during close combat attacks.
Entangle: Hits scored by weapons with the Entangle trait cannot be
negated by the Parry trait. In addition, if the hit roll for an
Entangle weapon is a natural 6, any Reaction attacks made
