There are two optional boss fights in Siofra River underground region and the Nokron region. Both of these bosses are Ancestor Spirit and the Regal Ancestor Spirit. To unlock both of these bosses, players need to activate flame pillars outside their corpses. This guide will help you find the Flame Pillars for both of these Ancestor Spirit bosses; one in Siofra River (Ancestor Spirit) and the other in Hollowhorn region (Regal Ancestor Spirit).

There are eight Flame Pillars in the Siofra River area starting from the Siofra River Bank Site of Grace. Lighting all these Flame Pillars will let you fight the Ancestor Spirit Boss.
- The 1st Siofra River Flame Pillar is found right in front of the area unlock Site of Grace.
