Frenzied Shrine

The Frenzied Shrine provides a powerful combat boost by adding a 25% bonus to Attack Speed for 2 minutes.

During beta testing this shrine boosted Critical Hit Damage by 25% as well as attack speed, but that was deemed too powerful and the bonus was limited to Attack Speed for the game's release.

The Attack Rate boost is powerful on its own, and this shrine can be useful as a sort of equipment upgrade preview, since 25% is roughly the AS boost provided by 3 pieces of equipment boosting Attack Speed. (Many of which provide +8-9% Attack Speed.)

Shrines in Diablo III

Shrines are randomly-located, randomly-spawned objects that characters can click to receive temporary buffs. Shrine effects pass to all players in the area when they are first triggered. All shrine benefits last for 120 seconds, and characters can benefit from multiple different shrines at once. Shrine bonuses and durations do not stack, and hitting a second shrine of the same type will simply reset the time to the full two minute duration.

• Blessed Shrine - Reduces all damage taken by 25% for 120 seconds.
• Empowered Shrine – Increased resource regeneration and reduced cooldowns for 120 seconds.
• Enlightened Shrine - +25% Experience gain from monster kills for 120 seconds.
• Fleeting Shrine – Increased movement speed and adds 25 yards to gold and health orb pickup radius for 120 seconds.
• Fortune Shrine - +25% to Magic Find and Gold Find for 120 seconds.
• Frenzied Shrine - Increases attack speed by 25% for 120 seconds.
