Samadhi Fire Crystal is a material you can use to craft weapons to make The Destined One more powerful, and it’s dropped by a few bosses. You’ll need 3 of them to craft the Legendary Staff of Blazing Karma, which also requires x3 Gold Tree Cores and 30,000 Will. Finding the exact locations of bosses can be confusing in this game, so here are the locations you can find them to obtain this resource.
3 Samadhi Fire Crystal Location: Craft Legendary Weapon: Black Myth Wukong
Samadhi Fire Crystal is dropped by Flint Chief, Flint Vanguard, and Mother of Flamlings.
Flint Chief is a Yaoguai Chief that you can find if you start at Furnace Valley's Valley Entrance Shrine. Keep going and look for an area with lava. From here, go right and you'll see more lava. Keep going and the Flint Chief boss should appear, ready for a fight.
The Flint Vanguard is another fiery boss that can be found near the Ashen Pass III temple of the Field of Fire. Turn around and walk along the rocky path. When you come across two paths, take the right one and you will reach a location where you can see some scattered rocks with fire in them. They will soon unite to form the Flint Vanguard.
