Buy RS3 Marrentill potion (unfinished)
The Marrentill potion (unfinished) is a members-only Herblore item in RuneScape 3. Players make it by adding a clean marrentill to a vial of water. It takes Herblore level 9 to mix and gives 1 experience per potion.
This unfinished potion is a key step for four finished potions. Add bear fur at level 9 for a defence potion (3) and 45 experience. Add cadava berries at level 11 for a necromancy potion (3) and 50 experience. Add unicorn horn dust at level 13 for an antipoison (3) and 50 experience. Add sanguine matter at level 15 for an antisanguine (3) and 55 experience.
Marrentill potions (unfinished) are tradeable and noteable, so they are easy to stock up on for Herblore training. Buying them ready-made skips the mixing step and saves time when training low-level Herblore. Each one weighs 0.056 kg and can also be made in bulk at Livid Farm, 50 at a time, for 5,500 produce points.
The item can be disassembled too. It gives Simple parts most of the time and Variable components on rare occasions, with a base junk chance of 98.9 percent.
