Serum 207 (4)members

“4 doses serum 207 as described in Herbi Flax's diary.”

About this item

Serum 207 is a potion that can be made after reading the diary of Herbi Flax during the Shades of Mort'ton quest, by adding ashes to a tarromin potion (unf), requiring level 15 Herblore and yielding 50 Herblore experience. It can be used to temporarily cure the otherwise incoherent, afflicted villagers of Mort'ton in exchange for a reward, as part of the Shades of Mort'ton minigame. It can also be used on the lit fire altar inside the Mort'ton temple, requiring 20% sanctity, to turn it into serum 208, which can be used to cure the afflicted in return for better rewards. As the possible rewards for curing the afflicted include all the items required to make the potion, and the only other potions that can be made with tarromin are strength potions, which give the same experience but require limpwurt root to make, making serum 207 can be used as an inexpensive, albeit slow, method of training Herblore.

Its high alch value of 8 does not cover the 155 nature rune it would burn, so alching is a loss before the item itself is counted.

Measured with medians rather than averages, because one spike — an update, a streamer, a brief squeeze — drags an average around for weeks afterwards and makes everything since look ordinary.
