Slipshod Hammer 2014
Weapon, common
This large smith's hammer appears well-used and rough in make and maintenance. If you use this hammer as part of a set of smith's tools, you can repair metal items in half the time, but the appearance of the item is always sloppy and haphazard. When you roll a 20 on an attack roll made with this magic weapon against a target wearing metal armor, the target's armor is partly damaged and takes a permanent and cumulative –2 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10.
Properties
Light
A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.
Thrown (range 20/60)
If a weapon has the thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the finesse property.
