Liquid Rainbow is a Unique Consumable introduced in Season 15: Season of Hell’s Legacy and is connected to one of the season’s hidden secrets.
The item originally appeared in Diablo III as one of the materials used to create the Staff of Herding, although its purpose has changed for its return in Diablo 4.
Liquid Rainbow can be obtained through Season Rank progression, while additional copies have also been reported as rare drops throughout Sanctuary.
How To Get Liquid Rainbow?
The most reliable way to get Liquid Rainbow is by progressing through Season Rank V, where one is included among the rewards for completing the rank.
This provides every Seasonal character with a straightforward way to obtain the item without relying on a random drop or completing a hidden objective.
Additional Liquid Rainbows can also appear as rare world drops, although there is currently no specific activity that guarantees another one.
Because of this, completing Season Rank V remains the best way to obtain your first Liquid Rainbow before relying on additional random drops.
Can You Get More Liquid Rainbows?
Liquid Rainbow is not limited to the copy obtained from Season Rank V, allowing additional ones to be found after receiving the guaranteed reward.
These additional copies can appear as rare drops while completing other activities, but there is currently no reliable method for specifically farming them.
It is therefore worth keeping any additional Liquid Rainbows you find, especially since each one provides another opportunity to use the item’s unique effect.
Liquid Rainbow Uses
Liquid Rainbow is primarily used to gain access to Whimsyshire, the colorful secret area returning from Diablo III.
Unlike its original appearance, the item does not need to be combined with other materials through the Horadric Cube before it can be used.
We cover the requirements, enemies, encounters, and rewards found inside the area separately in our Whimsyshire guide.
Is Liquid Rainbow Used in Horadric Cube Recipes?
Despite being a classic Diablo crafting material, there is currently no confirmed Horadric Cube recipe requiring Liquid Rainbow in Season 15.
Items such as the Black Mushroom have also returned, leading to speculation surrounding the Staff of Herding and other hidden recipes.
Until another recipe is discovered, Liquid Rainbow’s confirmed purpose remains connected to accessing Whimsyshire.
Verdict
The easiest way to obtain Liquid Rainbow is through Season Rank V, which guarantees one without requiring you to hunt for a rare drop.
Additional copies can also be found while playing, although there is currently no dependable activity for specifically farming them.
Its main purpose is tied to Whimsyshire, making it worth holding onto any additional Liquid Rainbows you happen to find during Season 15.
