In Elden Ring, having strong Spirit ashes in your arsenal will turn the tide of an engagement during major boss fights. Players will discover several Spirits across the Lands Between, but legendary Spirit ashes have better attack sets and can withstand more damage. 

The Cleanrot Knight Finlay legendary Spirit ash is located near the Prayer Room Site of Grace at Elphael, Brace of the Haligtree. This item is located inside a treasure chest, and the area is heavily guarded by Cleanrot Knights. Once you reach the Prayer Room, make your way down to the lower floor to find Cleanrot Knight Finlay’s legendary Spirit. 

After reaching Miquella’s Haligtree, use the branches to navigate down to Elphael, Brace of the Haligtree. Players will have to defeat Loretta, Knight of the Haligtree, to unlock the Prayer Room Site of Grace. You can avoid the enemies and head straight for the room shown in the image below to claim the legendary Spirit Ashes.

Players can summon Cleanrot Knight Finlay by using 127 FP. This Knight performs both magic and melee attacks and is perfectly suited for situations where you are outnumbered. If you haven’t unlocked Miquella’s Haligtree region, then start by collecting both Secret Haligtree Medallions and use them at the Grand Lift of Rold to visit Mountaintops of the Giants, West.
