The southern side of the Volcano in the Exiled Lands, around the Obsidian sources in map grids F–G/13–14.
Gather Raw Ash from Obsidian around the southern side of the Volcano when you need the material for recipes such as dye or alchemical production. The community wiki places this source around map grid F–G/13–14 and reports that a sickle seems to yield best from Obsidian. The Volcano is a hazardous heat environment, so enter with heat protection and a clear exit plan; do not treat this as an early-game detour. Raw Ash also has other sources, including specific creature loot and a camp interaction, but this route targets the Obsidian deposits directly. Back at base, check the live recipe at your Firebowl Cauldron, Alchemist’s Bench, or other listed station before committing the stock, because the material serves several recipes and recipes may differ by station or version.
Heat protection and supplies suitable for a hazardous Volcano trip.
A sickle for harvesting Raw Ash from Obsidian, plus room for the collected material.
A base crafting interface that displays the recipe you intend to supply with Raw Ash.
Choose the Raw Ash recipe you are trying to supply and check its current station and ingredients at base before leaving.
Mark a route to the southern Volcano and bring heat protection; avoid carrying unrelated valuables into the hazardous area.
Find Obsidian deposits around the southern Volcano slopes in the F–G/13–14 area and identify them before harvesting.
Use a sickle on the deposits, the tool the wiki reports as the strongest option for Raw Ash collection.
Watch health and heat exposure while moving between nodes; break off the harvest and retreat if protection is failing.
Return with Raw Ash and sort it from other volcanic materials before loading a station.
Use the current recipe interface to route the ash into the chosen alchemical or dye production instead of spending it automatically on another recipe.
Record the stock remaining after crafting and make another trip only when the next batch justifies a return to the Volcano.
Farming tips
The wiki also records smaller alternate sources, including some NPC loot and a collectible bag by the Pit of Yog in Darfari camps; treat those as alternate opportunities, not guaranteed bulk supply.
Raw Ash participates in multiple recipes, so storing it separately helps avoid losing track of material earmarked for a specific craft.
Repeat, collect and use
Repeat the Obsidian route when you have a defined recipe need. Collection quantities depend on the deposits and harvesting conditions, so use your actual inventory to size each trip.
Common mistakes
Going into the Volcano without heat preparation or an escape plan.
Using the wrong harvesting tool when the intended target is Raw Ash from Obsidian.
Assuming Raw Ash has only one use and spending the entire stock before checking the other current station recipes.
When to stop or switch
Return once you have enough Raw Ash for the recipe batch you verified, or immediately if heat exposure or enemy pressure makes the route unsafe.
