Ash potion (unf)

Ash potion (unf), more commonly called an Unfinished ash potion, was an unfinished potion made via the Herblore skill. Players could make it by using ashes on a vial of water if they had reached a certain point in Shades of Mort'ton. Tarromin could be added to it to make it Serum 207. It was used primarily in the quest that is required to make it, Shades of Mort'ton.

On 17 October 2012, unfinished ash potions were removed from the game and replaced with tarromin potion (unf). They are now called "old potion" in QuickChat.
