Hammer of the Ancients (Diablo III)

Hammer of the Ancients is a Secondary skill.

In-game
When invoked, slams the ground, hitting a 6 yard radius circle 6 yards in front of the Barbarian (so technically, it is not a cone, and there is a chance that the foes directly to the left and right of the player will not be hit). Bonus Critical Hit Chance is calculated based on current Fury (before subtracting the skill cost), therefore it always has at least some bonus.

Visually, it causes a massive golden mace to appear above the Barbarian, which they slam straight down into the ground in front of themselves, where the mace remains crushed for a moment. Note that this skill is targeted at the enemy, not at the location.
