Plague Flail

Close Combat Weapon.
Attacks made with a Plague Flail gain +2 Strength and +2 Armour Penetration. Unless using another weapon, the wielder of a Plague Flail suffers -1 Defensive Skill.
In addition, at Initiative Step 10 (regardless of the wielder’s Agility) the wielder must choose an enemy unit that it could normally allocate Close Combat Attacks towards (including Supporting Attacks). The chosen enemy unit suffers a hit with Toxic Attacks. This hit is considered to be a Special Attack.
This weapon cannot be enchanted with Weapon Enchantments from the List of Common Special Items
