Earthenflail

This roughly hewn wooden haft is lashed with gut and rope to a hefty boulder. This +1 shattering heavy flail can strike devastating blows against objects. As a swift action, however, the wielder can suppress its shattering property until the beginning of his next turn, allowing the head to phase through earth and stone. This allows the wielder to ignore cover or partial cover (but not total cover) provided by objects or structures made of earth or stone; however, while suppressed, an earthenflail cannot harm objects made of these materials. Cover provided by other sources is unaffected.
