Buy RS3 Sanfew serum (4)

Description

The Sanfew serum (4) is a four dose potion in RuneScape 3. It combines the effects of a super restore and an antipoison in one item. Each dose restores Prayer points and cures poison, so it saves inventory space on long trips.

At level 99 Prayer, one dose restores 337 Prayer points. With a holy wrench, that goes up to 356 points. The antipoison effect lasts 86 seconds per dose. This makes the serum a strong pick for fights where poison is a threat.

Making this potion yourself takes work. You need level 65 Herblore and the Zogre Flesh Eaters quest. You must add unicorn horn dust, clean snake weed, and nail beast nails to a 3-dose super restore, in that order. Snake weed cannot be traded, which makes the potion harder to craft. Mixing one gives 160 Herblore experience.

The Sanfew serum (4) is a members item. It can be traded, noted, and disassembled. It weighs 0.02 kg and does not stack. You can also combine six or more doses with a potion flask to make a Sanfew serum flask.
