This page offers a guide on how to find and light all 8 obelisk braziers in Siofra River in Elden Ring.
How to light all Braziers in Siofra River
To gain access to the Ancestor Spirit fight, you’ll need to light up eight Hallowhorn Braziers. These are scattered around the area, and can be lit up by interacting with them.
Obelisk Brazier 1
Obelisk Brazier 2
The second brazier can be found up the hill to the west of the Siofra River Bank site of grace.
Obelisk Brazier 3
The third brazier is northeast of the Siofra River Bank site of grace. It can be found on a piece of land with a ruined archway on it in the shallow water area just past the large bridge. It’s worth noting that this area has a couple of ancestral follower warriors who have bows, they’ll charge up their shots and if you’re hit by them, you’ll take significant damage.
The best way to deal with this is to take a wide berth either side of the brazier, and come from behind it. That way, you can use the pillars around there to break line of sight.
Obelisk Brazier 4
The fourth brazier can be found near the edge of the eastern cliff, east/southeast from brazier 3. Once again, a large group of ancestral follower warriors will be here, either rush there on your horse and activate it then leave, or slowly lure them out, and defeat them.
Obelisk Brazier 5
The fifth brazier can be found just southeast of the Worshipper’s Woods site of grace, which is northeast from Siofra River Bank site of grace.
Obelisk Brazier 6
The sixth brazier can be found just west of the Worshipper’s Woods site of grace, which is northeast from Siofra River Bank site of grace.
Obelisk Brazier 7
The seventh brazier can be found on the right of the road as you head north from the Worshipper’s Woods site of grace.
Obelisk Brazier 8
The last brazier can be found on the cliff to the west of brazier 7. There are quite a few ancestral follower warriors as well as some rats around here, so be careful.
Once all the braziers have been lit, head back to Siofra River Bank site of grace, and head up the stairs to Hallowhorns Ground. At the end, you’ll see a carcass, interact with it to be teleported to the Ancestor Spirit boss arena.
