Polearm Mastery

Members of the Crane Tribe value distance, grace and a single overwhelming blow over the close grappling form advocated by the Bear Tribe. Though the two clans were wary of one another for many generations, recently the nomadic peoples have commingled and now share their powerful techniques with all that would learn. Crane warriors evolved their pole arm technique from dealing with mounted raiders and fighting in the shallow river waters found in the steppe. A master of the pole arm avoids physical contact with his opponent until he can land a single killing blow.

• When equipping a polearm class weapon, enhances attack damage and attack rating with chance of critical strike doubling physical attack damage. Since conversion of physical damage to another damage type occurs after it is applied, it can also double the converted damage of Berserk (both the skill itself and its synergy bonus to Concentrate).
• Mastery critical strike does not apply when using Sacrifice charges.
• Mastery critical strike is mutually exclusive with Critical Strike and Deadly Strike: if one is successful then the others aren't applied. Combined % chance of double physical attack damage is as follows:

Two sources	100 - (100-CS)*(100-MCS)/100
	100 - (100-DS)*(100-MCS)/100
Three sources	100 - (100-CS)*(100-DS)*(100-MCS)/10000 [1]
