Rampage creates a Raging Tempest around you for 4 seconds, dealing (X% Attack Power) damage to all enemies within 8 yards every second. (Insert ICD or modify damage as needed.)
While Raging Tempest is active, your movement speed is increased by 15%.
4-Set Bonus: “Unyielding Carnage”
Each Rampage increases your Mastery by 2% for 10 seconds, stacking up to 8 times.
At maximum stacks, your next Rampage unleashes a Raging Smash, dealing massive damage to all enemies in front of you and refreshing stacks back to 0. (So players can think about positioning.)
