Serum 207

Serum 207 is a temporary cure for the afflicted villagers of Mort'ton, who are otherwise incoherent. A player who has read the Diary of Herbi Flax during the quest Shades of Mort'ton, and has at least 15 Herblore may produce it by adding clean tarromin to a vial of water and then adding Ashes, giving 50 Herblore experience.

The potion may be used on an afflicted villager, who will temporarily become a Mort'ton local and reward the player. In addition to Shade keys and Level 1 clue scrolls, the possible rewards include all the items required to make the potion, allowing the process to be repeated for an inexpensive, if slow, method of training Herblore. It may also be used on the sacred flame in the Temple of Mort'ton to produce serum 208 (see the Shades of Mort'ton minigame for more on that process). Serum 208 is required during the quest, and will give greater rewards when used on the afflicted.

Because ashes are cheaper than the other ingredients which may be combined with Tarromin, which is itself a cheaper herb, the potion is a Herblore training option with an excellent price-to-experience ratio. To dispose of the potions afterwards, they can be withdrawn from the bank in noted form and dropped, or disassembled manually or on a machine. Alternatively the vials can be emptied. The quickest way to do this is to drag a vial of Serum 207 over to the ability bar, so that a full inventory can be emptied in a few seconds by repeatedly tapping the key the vial is set to. Decanting noted vials into 4 doses at Bob Barker in the Grand Exchange further quickens the emptying of large quantities of Serum 207. Or you could keep the empties and dispose of the 4 dose vials another way.

If emptying the vials without using the ability bar, the quickest method is to empty them per column of vials in inventory. Start at the top of a column, right click on a vial, select the empty option. Selecting the empty option moves the mouse pointer down about one row in the inventory, and a little practice can easily have it end up positioned over the next vial, whereupon the process is repeated. This greatly reduces the amount of time spent moving the mouse. Given that empty vials have a GE price of 2 coin(s) there are likely to be more profitable ways to spend time.

Cost-benefit analysis of curing[edit | edit source]

Simply subtract the current production price (seen below) from the current sale price of the reward items to see that players can easily break even by curing, and, given a few favourable results from any received clue scrolls, could even profit greatly (see the God robes sets).

In one test run where over 700 (4) dose serum were used, the number of tarromin herbs rewarded was actually more than the number used to make the potions, generating a 100%+ profit. On the downside, the endeavour took nearly a week and a half of heavy playing to complete. (Note: ALL of the items were retained. A considerable amount of time could be saved by dropping empty vials and other undesired items.)

Unfortunately, as curing or "using" the potion requires a massive time and energy commitment, especially for players who have made thousands of these potions, and given that the money spent is generally not monumental to begin with, the loss of money is widely held as acceptable. If the player is so inclined, however, the method is viable.

Update history[edit | edit source]

The update history project is a work-in-progress – not all updates to this topic may be covered below. See here for how to help out!
  • patch 5 February 2013 (Update):
    • Players can no longer try and create Serum 207 without being at the correct stage of the quest.

Trivia[edit | edit source]

  • Serum 207 used to be tradeable until an update in early 2008[which?] where this ability was removed.
  • Originally, players may have found it economically easier to use an ash potion (unf), but with the update on 17 October 2012, this item was removed. Players must now use a tarromin potion (unf) with ashes.
  • Originally Serum 207, like all untradeable items, could not be noted.
