Verac's flail

Verac's flail is a flail that is part of Verac the Defiled's set of barrows equipment. To wield Verac's flail, a player must have 70 Attack. 
If Verac's flail is wielded along with all of the other pieces of equipment in Verac's armor set , the player receives a special effect. Attacks with this special effect have a chance of hitting through an opponent's defence and prayer, allowing for frequent, consecutively unignored hits against high defence monsters. With the set effect, this can be considered one of the best weapons for PvP Combat. This weapon cannot be made using the Smithing skill. 
Verac's flail is also a fairly popular choice for killing waterfiends and the Kalphite Queen .
