The bonfire pits are all located in places visited during Scylla's Grove missions, so this challenge presents quick little side objectives to those other goals. The relevant missions are: * Professor Nakayama, I Presume? - Story mission leading to Roothill Village * Ol' Pukey - Side mission * The Rakk Dahlia Murder - Side mission involving Low Gut Rut Reaching each fire pit requires traversing areas populated by savages. The fire pits are then ignited by interacting with them.
