In Wuthering Waves, you'll need a ton of Ascension materials to Ascend all of your characters. One of these important materials that you'll want to collect to max out both Calcharo and Taoqi is Iris, so let's take a look at how to get it.
All Iris Locations and Farming Route with Animated Minimap Guide | Wuthering Waves
There are a total of 65 Iris locations to find in the world. Most of these are located in the Fallen Grave area in the southeastern part of the current map. On the map below you can see all the Iris locations marked with stars.
Farming irises here is pretty quick; you can just do this circle every 24 hours on reset and get all the irises you need pretty quickly. If you want to branch out a bit, you can also find a handful of these flowers a bit further north in the Waving Battlefield. All iris spawns in this area are marked with stars on the map below.
There are other Iris spawns on the map, but they are much further apart and not really worth it if you plan on doing this farm once a day. However, there is another place where you can get a bunch of these blue flowers at once: the Shifang Pharmacy in Jinzhou.
