Inna's Mantra

Inna's Mantra (previously Inna's Grandeur) is a Monk class item set in Diablo III.

This set is named for Inna, goddess of the sky within the Sahptev religion.

The set requires a character level of 60 to drop, and can only drop at Torment difficulty.

Due to the item type composition, it is possible to combine this set with another if needed.

Pieces
The set consists of seven pieces, six of which are required to complete it, and two of them are Monk-specific.
 * Inna's Favor (Belt)
 * Inna's Hold (Gloves)
 * Inna's Radiance (Spirit Stone)
 * Inna's Reach (Daibo)
 * Inna's Sandals (Boots)
 * Inna's Temperance (Pants)
 * Inna's Vast Expanse (Chest Armor)

Set Bonus:
 * Increases the passive effect of Mystic Ally and the base passive effect of the Mantra by 100% (2 pieces)
 * Gain the base effect of all four Mantras at all times. You gain 5% damage reduction for each Mystic Ally you have out. Your Mystic Allies no longer take damage (4 pieces)
 * Gain the passive abilities of the five runed Mystic Allies at all times. Attacking enemies creates your chosen Mystic Ally that lasts 15 seconds, up to 10 Mystic Allies. The damage of your Mystic Allies is increased by 3000% for each Mystic Ally you have out (6 pieces)

The first bonus affects all bonuses of the Mystic Ally except the plain damage done and 'on hit' effects; activated bonuses are also unaffected. For Mantra, it only applies to unmodified passive effects, without a Skill Rune. With two Mystic Allies, one will, in fact, gain a quad bonus: for example, +40% (10% x 2 x 2) damage with Fire Ally rune and The Crudest Boots.

The second bonus grants, in fact, all four Mantras (fully benefit from all enhancements), but since the Monk can only have one Mantra as a skill choice, only one of these Mantras can be empowered with Skill Runes, and only passive effects are given: only the currently chosen Mantra can be empowered with active effect.

With The Crudest Boots and Fire Ally rune, the total amount of Allies goes up to 20. With Unity, these Allies are sufficient to cap the skill's maximum bonus.

Note that if Enduring Ally rune is manually chosen, the cooldown of Mystic Ally will increase to 50 seconds. Otherwise, it will remain at 30 seconds.

Each Ally will deal the Elemental Damage type respective for its skill rune (two out of five runes deal Physical damage, one Cold, one Fire, and one Holy).

Development
Prior to patch 2.2.0, the most significant bonus of this set was the Spirit cost of Sweeping Wind reduced by 70 (to 5), making it almost free to cast.

As of 2.2 and until 2.4, the 6-piece bonus allowed Mystic Ally to cast Cyclone Strike, Exploding Palm, Lashing Tail Kick, Seven-Sided Strike, and Wave of Light when the Monk did.
