This enormous greatclub bears thick patches of rusted metal bracing a spiked stone weight set within the gnarled head.

This Large +1 adamantine greatclub can only be activated by a bearer who has a Strength of 21 or higher and the Power Attack feat.
When it is activated, the next attack you make with a dwarf crusher in that round against a dwarf, a construct, or a creature that has the earth subtype is treated as a touch attack. You must also take at least a –5 penalty on this attack roll using the Power Attack feat in order to gain this benefit. This effect functions three times per day.

Prerequisites: Craft Magic Arms and Armor, bull’s strength, giant.
Cost to Create: 4,500 gp (plus 10 gp for base item), 360 XP, 9 days.
