Among the many consumables in Elden Ring Shadow of the Erdtree we have Iris of Occultation. This item is exclusive to the DLC so you won’t find it in the Lands Between.
Iris of Occultation are used to power up a Great Rune but they primarily acquired to earn unique items during certain questlines.
There are three Iris of Occultation in Elden Ring Shadow of the Erdtree.
Where To Find Iris Of Occultation
The three Iris of Occultation are found in Fort of Reprimand’s basement, Scadutree Base, and from an Ulcerated Tree Spirit in the Church District.
Fort of Reprimand Basement
The first Iris of Occultation is in the basement of Fort of Reprimand. You need to beat Omenkiller in the basement to get this one. Not a tough boss fight so nothing to worry about.
To get to this location, start from the Moorth Highway, South Site of Grace. Get inside the Fort of Reprimand and stay on the left wall to find a hole in the ground. That’s your ticket to the Omen killer.
Church District Ulcerated Tree Spirit
The second Iris of Occultation is acquired by defeating the Ulcerated Tree Spirit in the Church District.
You first need to drain the water from the Church District and then start at the Church District Site of Grace.
Head down the stairs to the south and use the level to trigger the elevator. The elevator will take you down. Head northwest and keep going until the Ulcerated Tree Spirit pops up from the ground.
Church District
The third Eye of Occultation is also inside the Church District. It is in the tunnel to the Scadutree Base which you can enter through the cathedral in the middle of the Church District in the Shadow Keep.
Go through tunnel until you reach a church. The Eye of Occultation (Iris of Grace) will be on the alter inside the church.
