Harvest ash ingredients at Raven Rock Mine

Exterior of Raven Rock Mine on Solstheim, in the Dragonborn add-on area.

Before you go

Travel to Solstheim and make your way to Raven Rock.
Find Raven Rock Mine and search the exterior ground around the entrance for Ash Creep Cluster.
Harvest the visible plants and check nearby terrain for additional specimens without entering unrelated dangerous areas.
At an Alchemy Lab, inspect Ash Creep Cluster’s effects using ingredients you have already learned or tested.
Combine it with a compatible ingredient to make a potion or poison, following the shared effect you want.
Keep the finished product for its practical use or sell it if your goal is Alchemy training and gold.

Keep Ash Creep Cluster separate from common mainland ingredients until you know which recipe you want to support.
Solstheim travel is most efficient when combined with other Dragonborn objectives in Raven Rock.

This is a plant harvest, so return after the game’s plant regrowth cycle if you need more. The amount available can vary with previous harvesting.

Do not search mainland Skyrim for this Solstheim ingredient; the route requires Dragonborn access.
Do not assume the plant shares an effect with an ingredient without checking the ingredient properties.
Do not make a special trip for a small harvest if a later Solstheim visit can collect it naturally.

Stop once you have enough Ash Creep Cluster for your intended recipes, or defer another trip until you have more business on Solstheim.
