Buy RS3 Harmony moss seed
The Harmony moss seed is a Farming seed in RuneScape 3. You plant it at the Harmony pillars in Prifddinas. You need level 75 Farming to use it. Each pillar takes one seed, and planting gives 165 Farming experience.
The moss grows in four stages. Each pillar is tied to a skill. The moss grows as you gain experience in that skill. Each stage needs 50,000 experience, so full growth takes 200,000 experience in total. Growth progress is permanent, and the moss cannot get diseased. You can change the pillar's skill once per day, but this removes your old progress.
When the moss is fully grown, you can harvest it for harmony moss. A normal harvest gives 1 to 5 moss, and each one gives 1,133.3 Farming experience. A perfect juju farming potion can boost the yield up to 15. A Tirannwn quiver 3 or 4 gives a 10% chance for one extra moss.
Harmony moss matters for players chasing goals. Harvesting 50 moss unlocks the of the Meilyr title. Harvesting while the Voice of Seren is active in the Meilyr Clan counts toward a hard Tirannwn achievement.
