The "Raiment of the Infinite" is a unique chest armor in Diablo 4, obtainable by defeating enemies, opening chests, or breaking objects within the game world. It can drop at any Difficulty Tier, but has an increased drop rate in Torment tiers. You can also target-farm it by summoning and defeating Echo of Varshan. This item is part of the loot pools for both Echo of Varshan and Lord Zir. To encounter these bosses, you will need to collect specific summoning materials by completing Diablo 4 endgame activities. Tormented Uber Bosses, introduced in Season 4, offer the best chances for obtaining unique items, but they require Stygian Stones from The Pit.

When equipped by a Sorcerer, Raiment of the Infinite pulls nearby enemies closer and stuns them for 2 to 3 seconds after Teleport is used; however, the Teleport's cooldown is increased by 20%.
Other affixes that come with this armor include:
For players seeking to optimize their character builds and acquire powerful gear quickly, the option to buy Diablo 4 Items: Raiment of The Infinite has emerged. This allows adventurers to bypass the often-grindy process of farming for specific pieces like the Raiment of the Infinite, enabling them to immediately enjoy the benefits of enhanced stats and unique effects in their gameplay.
Legendary items in Diablo 4 have special gameplay-modifying affixes that are randomly rolled, meaning they can appear on different items in different slots. Unique items, on the other hand, have fixed affixes with no randomness to their stats.
With the introduction of Season 4, affixes can be added to items through a system called Tempering. Recipes that add affixes drop randomly, and once acquired, can randomly add an affix to an item from a selection of four. Ancestral items can be tempered twice, allowing for the addition of two new affixes. Unique items cannot be tempered.
Greater Affixes are affixes that only Ancestral items can have. These affixes always roll the maximum value, increased by 50% compared to normal items. An item can have multiple Greater Affixes, which can be further enhanced through Masterworking. However, items with Greater Affixes cannot be crafted or re-rolled.
The random nature of affixes has raised concerns about excessive RNG (Random Number Generation). The tempering system lets you randomly add an affix to your item from a list of 4 affixes. This means you can easily get the wrong affix, and you can re-roll it, but only a limited number of times called Tempering Durability. If you use up all your re-rolls and still don’t get a good affix, the item is destroyed. Also, levels 4, 8, and 12 of the Masterworking process involve randomly adding an affix to an item, which may affect the same affix multiple times.
Multiple Greater Affix items are rare. Some players feel that if you have multiple high stats, especially perfect stats, the remaining stat will have a near-zero chance to be high as well. The tempering system may ruin items when you get these "uberish" items.
