Flails
Flails are one of the newest weapon types added to the game, and not many exist at the present time. Flails skill scales with brawn and senses for accuracy and skill, reflexes for speed, and brawn for bonus damage.
Good Things About Flails
Most flails are PC-, making them the only unblockable melee weapons. They also speedcap rather easily, though some seem to have speedcaps of their own making them essentially melee guns that don't use ammo.
Not So Good Things About Flails
Several flails have the ability to get stuck in your opponent's face mid-battle. How is this a bad thing, you ask? Well, to continue swinging at their noggins, you'll have to pull the flail out of their body first. This may take a while if you roll poorly. Also, as they are PC-, they cannot block your opponent's attacks, forcing you to rely on your dodge and soaks to survive.
