Although there are many gifts from the Great and Ancient King Bul-Kathos, the greatest of these is the secret of steel. Raw iron is hardened and made resilient, forged into weapons of honor and power. Most mortal swords are patterned after the blade first wielded by Bul-Kathos himself. Balancing offense with defense, it is the perfect weapon for the defense of Mount Arreat in the coming apocalypse. All Barbarian warriors learn the secrets of steel at an early age, yet few truly master the deadly elegance of the sword. Those few who do often disdain all other weapons.

• When equipping a sword 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 and Frenzy).
• Overlay normally displayed when successful may be obscured by others (which gave rise to the myth that poison damage prevents it from being applied).

Target overlay when critical damage is applied.

• 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]
