Scarlet Ore: An essential but relatively infrequent material in Core Keeper. High-end utility is applied during the crafting stage. Scarlet Ore, by itself, doesn't have much use other than crafting Scarlet Bars, which opens up a wide array of crafting possibilities and acts as one of the bottlenecks of your progression in the game. It is mainly used in the later stage of the game. A guide to finding it can be found below.

How to Obtain Scarlet Ore
- Locations for Scarlet Ore
Scarlet Ore is a rare ore in Core Keeper. First, Scarlet Ore is found in the Azeos' Wilderness biome and its sub-biome, the Mold Dungeon. To get to Azeos' Wilderness, you must first clear out the starting three bosses in Core Keeper:- Glurch the Abominous Mass
- Ghorm the Devourer
- The Hive Mother
- Mining Scarlet Ore
Inside the Azeos' Wilderness, Scarlet Ore can be found in Grass Walls, though you will have to break the grass walls to claim the ore. Further on, Scarlet Ores can be found in Mold Covered Chests in Mold Dungeon, dropping three to six units of the said ore.
