Dungeoneering/Herblore

Herblore in Daemonheim is only accessible to Pay-to-play.

You must have completed Druidic Ritual to mix potions within Daemonheim.

To clean herbs and make potions, you must be raiding a dungeon with complexity level 5+.

Cleaning Herbs
The process of cleaning a herb is exactly the same as outside of Daemonheim: find a grimy herb and, if you have the Herblore level to clean it, simple right-click it and select 'Clean'.

Potions
As with cleaning herbs, making potions in Daemonheim is very similar to making potions in the rest of RuneScape. You will need a cleaned herb, a secondary ingredient (gathered from the drops of monsters about Daemonheim, or from the smuggler in the starting room) and a vial of water to make a potion. Vials can be bought from the smuggler and filled with water at any of the frequent water points strewn around Daemonheim.

It is worth noting that some obstacles require a potion-boosted skill level to pass them. Ex: "You need a mining level of 103 to mine this rock."

You cannot make a naturalist's potion to boost your Herblore level, then make a higher potion with the boosted Herblore level. This doesn't make much sense, and leaves no purpose for boosting your Herblore level, unless you are only able to in order to meet door-opening requirements. For example: Attempting to make a strong melee potion at level 72 will get you the message; "You need an Herblore level of 73 to make this potion". Making a weak naturalists potion will boost your level to 77 / 72 but will still yield you the same message "You need an Herblore level of 73 to make this potion". This could possibly be a bug that has yet to be fixed by Jagex.
