Threatening Shout

Threatening Shout is a Tactics skill. It resembles the skill from Diablo II, and can be enhanced to fuction like  or.

In-game
Like all Tactics skills, Threatening Shout is an instant cast, and can be used at any time, including while on the move or while performing any other attack.

Unlike similar skills of other classes, Tactics shouts are not mutually-exclusive, and may be combined with each other.

Runes

 * Affected enemies are also slowed by for the duration.
 * Instead of dealing reduced damage, affected enemies take increased damage from all sources for  seconds. Does not stack from multiple casts, even from different players.
 * Affected enemies are badly shaken and have a chance to drop a Health Globe regardless of their current Life.
 * Affected enemies turn their attention towards the Barbarian, becoming taunted for seconds.
 * Each affected enemy will flee uncontrollably in Fear for seconds.

Non-rune enhancements

 * Skull of Resonance (Legendary Helm): gives a chance to affected enemies.
 * Blade of the Tribes (Legendary Two-Handed Mighty Weapon): on cast, summons both an Earthquake and an Avalanche.
 * Horde of the Ninety Savages Set (Set bonus for 2 pieces): doubles the effect of the Threatening Shout. With Terrify rune, Feared enemies take double damage.

Passives

 * Inspiring Presence: doubles the duration and, when cast, also increases Life regeneration for the Barbarian and all allies within 100 yards by 3% of their maximum Life per second for 60 seconds.

Development
Originally, Grim Harvest rune also allowed shaken enemies to drop gold and items as if they were killed (much like the original Find Item skill). The chance to drop items was much lower than that of dropping health globes and gold, could only be performed once on each enemy, and would only affect the Barbarian's own loot. In Greater Rifts, this could only drop health globes.

Prior to patch 2.4, Lord of Bells could also use this skill.
