Weight of the Mountain Rune (I)

+100% Special Ability Damage.

Each Basic Attack cast reduces Earthstrike's cooldown by 0.8 seconds.

When a Stun you inflicted ends, the enemy is left Fractured for 8 seconds, taking +250% Critical Hit Damage from you.

Each cleared boss encounter of level 40 and higher has a 2% chance to drop a rune (1.5% on mini-boss stages). On Inferno 0.5% of those runes are Set Runes before the stage's loot bonus and Item Find, which raise it; on Normal and Nightmare no Set Rune drops. Only runes for the current hero's class drop.
